How to Activate iPhone 4.0 Firmware beta with UDID

Ads
on April 10, 2010

Last year we provided a procedure to Activate iPhone 3.0 beta and as promised, we are back with a tutorial on how to active the iPhone 4.0 Firmware for your device which will enable you to install the firmware and test it.

Activating the firmware is equivalent of to getting the UDID of your device registered in the iPhone developer program so you are legally able to test the new firmware on your device without any syncing problems with iTunes.

Register the Unique Device ID (UDID)

Now you won't be able to do this unless you have a iPhone developer account yourself which costs $100 a year; or have a friend who is enrolled into the program and willing to do the favor. But we here are giving you a chance to get this for free. Here is what you have to do:

  1. Connect your device (iPhone or iPod Touch) to the computer.
  2. Open iTunes and click on the Summary for the device.
  3. Hover the mouse over to where it says 'Serial Number' and click on it such that to make it toggle into Unique Device ID (UDID).
  4. Note down the UDID very carefully; better write it down somewhere.
  5. Head over to this form, enter the details and wait for a couple of hours.
  6. Comment on this post and tell us which one of the 7 tentpole features for iPhone OS 4.0 is your favorite.

That's it! Carefully follow the steps above and your Unique Device ID will be registered.

Important: This is a first-come-first-serve offer so make sure to follow the steps accordingly. Those who fill up the form but do not leave a comment as mentioned would not be entertained. Oh and please use the same name/email in the comment and activation form.

Update: The iPhone 4.0 beta 2 firmware is now available for download. Links for developers and users have been provided.

    I'm extremely excited about the multitasking. At first I was a little hesitant because of slow performance and smaller battery life, but it seems like they found a way around that and I can't wait to test it out.

  • Arturo

    Multitasking & Folders!!

  • mukulchandail

    Real nice of you guys..thanks a lot ^_^
    btw, from the 7 tenpoles, I like the multitasking and folder feature a lot. Now I would be able to freely move between the apps and have more empty space on my home-screen.I was dying for this feature. And there's a home-screen background too, yay.
    However, it wasn't fair of Apple to restrict the multitasking to the iphone 3gs and ipod 3g only(I feel terribly sorry for the 3g owners,) :(

    • robertholcroft

      Couldn't agree with you more regarding the 3G owners, im just interested to see what other features will have been left out.

  • Dan Kuhlmann

    Just a question btw:
    How long will it take to get an answer and after this registration I am able to use the 4.0 like a full version? :)
    Sorry for that but I do not know why to register the UDID

    And at least: Thank you for this stuff!

    • Mohammad_s

      the beta version of OS4 is just available to apple developer members( paied 100$) that has access to download the OS and ability to register up to 100 UDID.itunes will check your UDID after you upgrade your frimware to 4 and activate your firimware only if your UDID is registered.

  • Manuel Magalhães

    Folders and Books for me.

  • mukulchandail

    Real nice of you guys…thanks a lot ^_^
    btw, my favorite feature from the tenpole has to the multitasking, followed by folders. Now I will be able to freely switch between the apps and there'll be a lot of empty space on my home screen too. I was dying for this feature to show up. And now we can add background to the home screen too. Hurray!
    However, it wasn't fair of Apple to restrict multitasking only to the iPhone 3gs and iPod touch 3g. (I feel terribly sorry for the iPhone 3g users.) :(

  • Julián pikman

    • wilt0000

  • gamemaster700

    I was thinking that iBooks was going to be my favorite, but Multitasking must be the most breakthrough feature that Apple put in to the iPhone.

  • KeenanRobles

    ok thanks! ^^

  • http://www.facebook.com/gallionator Matthew Gallion

    My favorite feature will be Multitasking because I will use it all the time. I'll also use folders a lot so it'll be my second favorite.

  • danielwilson

  • Sina Hamedian

    I still don't have an email from you or a successful registration.
    But I do have an iBrick until I get a successful registration. :'(

  • jamespugliesi

    ahh I commented on the wrong page at first!

    I'd have to say I do like the multitasking tentpole the best. Not really because of multitasking in general either. Firstly I get annoyed with the Android users who say “oh yeah well we have multitasking” well not anymore. I am extremely excited to see how well it operates on the Iphone because of how they've incorporated it. What I mean by that is how they have written the actually multitasking codes for the apps right into the OS. That seems to be a brilliant idea. Now the apps can obviously run a lot lighter because of the coding already being run in the OS. To me that makes the multitasking tentpole a sure winner. If all works out well I can now respond to Android users with “well not only do we have multitasking, we don't have to be plugged into a charger to use it ;) ”

  • Kyle Deane

    The 7 Tentpole features i like are:
    1) Background tasking
    2) The gaming (game center)
    3) iBooks
    4) Folders
    5) Better Email (Unified inbox)
    6) The modifications to the Pictures app
    7) the backgrounds on the homescreen

    And I'm stoked for Multi-tasking!

  • farazalishah

    These 2 features is the best!

    Feature #1 – Multitasking: Finally as we reported earlier, the new iPhone OS 4.0 will give the user the option to run app services in the background such as audio, voIP and location.

    Feature #2 – Folders: The users will now be able to organize their apps into intelligent folders which raises the app-limitation bar from 180 to 2160 on the iPhone.

      Hi! I couldn't find out how to comment because in the box there was just an add, so I had to reply to a comment. Hope that's ok. My favorite is folders. Thanks much! Hope it works.

  • Luis D

    Folders and Multitasking are the 2 best but Folders is the best because new apps are dropped into the app store and you can quickly run out of room and you will have to delete apps for space. With the Folders, you can have 100's of apps and the iphone will categorize them for you. That is sweet.

  • Vernon Sullivan

    Very Nice !!! Thanxs !!!

    MY favorite is the background wallpaper and folders is pretty cool

        You can by registering a developers account, it's $99 a year. Don't install the new firmware without being sure it's registered. It will make your phone into an emergency call paper weight

  • joshvirata

    My favorite tentpole feature of the upcoming iPhone OS 4.0 is the folders feature. Long have I sorted my apps to the point where each home screen is like a folder, sorting apps by what they do and ones that are related. With folders it'd be great to have multiple folders with all these apps in and just expand them as needed.

    My favorite new feature for the new iPhone OS 4.0 is, of course, multitasking. Although I haven't tried the new function yet, by merely looking at the demo excites me. My second favorite would be folders because the user interface would be so much more organized as I am an organized person. Thank you very much for doing this.

    My favorite feature in the upcoming iPhone OS 4.0 is Folders. I think it is a very clever and initiative idea to integrate into the iPhone OS.

  • Matt Dahlke

    I am anxious to try out how the folder system works first hand. For a guy with a great number of apps, it certainly would help to have them a little better organized to save time paging through screen after screen. Though it may be presumptuous, I thank you in advance.

    All the best and I've already added your helpful site to my feedlist!

  • nathanikes

    I think the idea of a merged inbox as i have 4 email accounts. Thanks if i get the beta. :-)

    multi tasking and folders are my favorite!

  • Joachim

    THANKS!!! JUST INSTALLED 4.0 SUCCESSFULLY!!
    I DIDN'T GET A CONFIRMATION MAIL YET, BUT IM ON 4.0!! WORKS GREAT!!

    • gamemaster700

      HOW??
      Ive been waiting since yesterday for a email. do you think they added my udid?

      • Joachim

        Yeah ive been waiting too. After i posted my favorite tendpole, Saad Hamid posted that he registered some UDID's! So i waited till this morning, but still no confirmation. So i decided to give it a try and i installed OS 4 and it works!! It's very buggy though.

        If you followed the instructions carefully and Saad Hamid posted (after you posted) on this article that he registered some UDID's, i think its fine to install!

        And if you fail to install it, you can always unbrick your phone by entering DFU mode and restoring to 3.1.3. You get a error after restoring, but as of that moment you have to jailbreak with redsn0w or blackra1n.

  • michaelramsey

    My favorite tentpole is the Multitasking feature. I will be able to run a VOIP in the background so my 8 yo daughter can call be via WIFI on her ipod Touch, yea! Thanks for a great job and also with helping me with my iphone activation last year.

  • Nathan D

    My favorite tentpole is multitasking but becaus I have an iPod Touch 2g, I won't be getting that, so i guess I like the folders feature the best.

  • mariowe

    hope that i can also test the new firmware :)

  • Oliver Bloice

    i love the new multi-tasking features in 4.0!!!! but wises it worked on the 3G as well :(

  • Sydney Tsai

    Folders and unified inbox are the big feature for me.

  • Stephan

    I suggest three Feature:

    Multitasking, the option to disable 3G/Edge and one Unified Inbox. That´s great.

    Thanks for your work / registering the UDID

    Regards
    Stephan

  • Jake1124

    Folders for sure way easier to organize stuff great feature

  • Marisca Ionut

    The best feature it's obviously the multitasking, but, beacause i have a 3G, not a 3GS, the feature will not be available for me so for me the best feature it's folders. A very good way to organize the apps. Waiting for the UDID. Thank you!

  • Markus Doll

    Hey ya,

    don't you think, the one in charge has got to do other things then watching this site the whole day, to activate every single UDID that's requested here?

    Think about it, i'm looking forward to my activation, too…

  • David

    Multitasking is the best. Too bad for me as I have an iPod Touch 2G.

  • ianschoen

    Im really looking forward to the Folders function. Tho the game room would be awsome if it turns out ok :)

    • gamemaster700

      I didnt get a email so i guess im not activated yet, but theres people here who said they didnt get a email but are activate so im like WTF right now.

      • SuBReH

        I want to try it so badly….but im scared that ill brick my ipod touch cause i dont know if I can :|

      • gamemaster700

        yeah i dont want to risk it either because thats what happen to me last year with 3.0 and i had to unbrick it but it took so long. I just wish there was a way to check if your udid is activated yet.

  • Tyler Mosdell

    game centre is number one, offers the feature that brought the xbox 360 and ps3 to the top of people wishlists around the world

  • Tylerbetances

    I would like to thank the dev owners for taking there time to do this for everyone… but please everyone understand this is a beta test and that is to help dev's work out kinks for there app development so provide any feedback to help them out with this process as well as Apple in reporting bugs and suggestions.

  • harrypeters

    Hi Saad, i sent you my UDID and posted here yesterday and haven't got an email back yet… Have you run out of places?

  • Frugghi

    My favorite feature is folders It's better than categories!

  • predragrisovic

    I am still waiting for your response for my UDID activation…

    • gamemaster700

      your not the only one, ive been here since yesterday.

      • predragrisovic

        so, what should we do?

      • gamemaster700

        well theres really nothing we can do other than wait longer or risk bricking our iphones/ipods and putting 4.0 on to check if it works. other than that we cant make Saad and his crew activate our iphones/ipods unless we like spam the forms.

  • http://www.hackpassion.uk.tt/ Andrex

  • Brian Armstrong

    I'm most interested in the Game Center.

  • timdeville

    Im really looking forward to the multitasking as it will make the iPhone feel quicker and it will be great to stream audio from Spotify in the background, but Im also looking forward to smaller features such as the spell checking and the custom backgrounds.

    • gamemaster700

      sucks for us that have regular iPhone 3g :(

  • Pichit A.

    I like multitasking feature and hopefully it stable. Thanks you.

  • iHandy

    The Firmware is super, Multitasking and the Folders are the best.
    I think this is the best Apple update ever!!!

  • Blake Green

    my favorite feature is gonna have to be multitasking!

  • gamemaster700

    well theres really nothing we can do other than wait longer or risk bricking our iphones/ipods and putting 4.0 on to check if it works. other than that we cant make Saad and his crew activate our iphones/ipods unless we like spam the forms.

  • Collin

    My favorite feature has to be the folders, I like to have my phone organized and having folders is better than having the apps simply alphabetically.

  • Tyler

    My favorite feature of the iPhone OS 4.0 would have to be the multitaksing, even though it isn't supported on the iPod Touch 2G

  • timdeville

    I do think its a shame that OS4 doesnt have a shared storage space though for documents etc, that would be good.

  • stifler46bd

    i think the best feature is folders

  • dane 1535395699@gmx.xx

    folders na enterprise

  • dorabuhassera

    Hey,
    i really liked the folders!
    its will be easer to use the iPhone now.
    thanks for the UDID

    • gamemaster700

      did u get a email

      • dorabuhassera

        i only got email for verify my email
        when ill know that i can upgrade to 4.0?

  • Fabio Prosperini

    My favourite feauture for the OS 4.0 is Multitasking, I think that's this is what iPhone user wanted since the beginning :)
    Thank you for the UDID registration

    • gamemaster700

      did u get a email?

  • Andrey Balandin

    the coolest feature is the multitasking in the new 4.0 firmware!

    • gamemaster700

      …… for 3GS

  • iAlexChristo

    My favorite is multitasking but folders look great too.

    • justinvins

      same son

  • Damour0000

    My favourite is folders

  • Jordie

    the best feature is multi tasking

  • Stopher92

    has anybody tried to download and install the firmware before receiving a confirmation email? does it brick your device? i'm just gonna wait it out regardless..anyways, i appreciate what you guys are doing and understand that you're doing what you can with the time you have. i really do want to test this new firmware and i plan to send you guys my feedback on it to help :)
    thanks in advance. -Chris
    oh and even though i've already commented and shared my favorite feature, i'll say it again. i think multitasking will be the best and most used feature.

    • gamemaster700

      YES IM BRICKED RIGHT NOW, but unbricking right now.

      • Stopher92

        oh that sucks..i wish i wasn't so impatient lol

    • justinvins

      im wondering the same thing man

      • joey coulter

        I DIDN'T GET BRICKED!!!
        WTF
        anyway i'm loving the 4.0

  • Dave McKenzie

    The feature i am looking forward to is the multitasking!!! Im sick of having to close things down everytime i get a message etc and having to reload everything back up!

  • danielmooney

    The best in of course multitasking. Cant wait to compare to jailbroken multitasking.

  • Andrey Balandin

    how long does it usually take to get your UDID registered? does anybody know?? and if so do they e-mail you to confirm??

    • gamemaster700

      well ive been waiting since yesterday and still no response. I tried restoring it to 4.0 but it got bricked and says my udid isnt activated yet. unbricking right now :-

      • Tylerbetances

        How do you check if it's been bricked and if so how to unbrick it…. because when I try the 4.0 restore I get an error (13)

      • Joachim

        You have to put your device in DFU mode, then restore to firmware 3.1.3. After restore you get an error (don't worry, 3.1.3 is already installed on your device). Then Jailbreak your device with RedSn0w (Mac) or Blackra1n (Windows). After that your device is unbricked!

  • justinvins

    does anyone know if they were still doing this as of 8 pm yesterday or should I start saving up for a legit developers account? lol

  • Brad

    Multitasking is the best.

  • bobby12345

    I think the best feature would be the Game Centre, something to go against the xbox

  • heely1234567890

    hey i think folders was a very good feature.

    Multitask were wonderful BUT I was very sad that i need the 3gs for this feature. and hey thx for registring mi udid!

    cheers

    • SuBReH

      did you get a confirmation email? or did you just update it?

  • Marcel Heller

    Hey, i think the folders would be my favourite feature.

    Bye

  • sasis

    Folders

  • parhat

    I've sent the request about few hours ago.
    I've downloaded the firmware and tried to install it, but i got error 13 via itunes.
    that mean taht i have to wait some time, right. :)

    • ranibalaa

      i sent the reply 15 hours ago

    • andrex95

      No it mean that you can't install iPhone OS 4.0 Beta because you have a problem with your device.
      You must have iTunes 9.1 and Mac And as device an iPhone 3G, iPhone 3Gs,iTouch 2G,iTouch 3G.
      Bye
      Good Luck

      • parhat

        Yeah, you're right, i don't have the latest iTunes, i have to upgrade it now.
        Btw ma, i 've an iPhone 3gs and my device has no problem ( factory unlocked ), i've restored few hours ago.
        thanks

      • andrex95

        Are you a Registered iPhone Developer?? Can you activate my iPhone 3Gs?? Please..

  • albertico

    I think folders and the unified inbox are the best for me, I have a 2G iPod Touch.
    Thanks for the tutos

  • andrex95

    Hi
    My favorite features are folders and multitasking.
    Please activate my UDID.
    Thanks.

  • kingwefe

    Hi I'm waiting like a few people. I think that the multi-tasking will be most useful as you can still be on one app and look at others. I will wait for an email to confirm but if it doesn't work then I haven't lost anything

  • Sebastian

    my favourite feature is mutlitasking! right on time;)

  • predragrisovic

    +1
    My favourite is multitasking :D
    Please active my UDID!
    ThanksThanksThanksThanksThanks

  • predragrisovic

    Only install from MAC?! Can I install it from Windows?! :S

  • Sam Simonean

    The most important feature is #3, the unified inbox.

  • scottstory

    I've been waiting for folders for a long time. I think the iPhone is the most revolutionary device I've ever used – it is constantly improving functionality with each useful app. What burns me though is the inability to access more than 11 pages of apps. I know it's a lot, but there's got to be a way to better organize them. I'm all for spending $100 to be legit and get the beta now, but I'm not a programmer, so that money is fairly wasted.

    • ankito

      Do you want to share the cost? :-) if we find enough people who are willing to share the cost :-)

      • scottstory

        Definitely willing to share the cost. I'd have no problem contributing $20 towards it.

      • scottstory

        I got sick of waiting and just purchased the iPhone SDK Developer Program from Apple. It was $99 plus tax, but now at least I'm legit and maybe I'll learn how to make my own apps.

      • David Lim

        I was considering buying the program, but I'm skeptical. And yes, if you could spare slots I know that the people and myself would be very grateful. I'm still wondering why Saad hasn't replied yet… Hmm

  • CJ Mills

    folders, for sure.

  • Melchor Sandoval

    I think my favorite one will be multitasking. Really looking forward to all of them though.

    Thanks,

  • andrew

    multitasking is definitely the best feature added although it is not activated for the iphone 3g. therefore, the folders will be the best thing for my iphone

  • Stefan Engert

    Hi,
    I guess I like multitasking the most.

  • http://www.sizlopedia.com Saad Hamid

    Hello guys! as some of you might have noticed in the comments users have reported that activation for their device has already been done so I advise you to please stay patient. I am doing this alone and processing 600+ registrations takes time and brain power.

    I have 200 slots left and more developers are opting in to support this campaign so hopefully we shall be cater for more. Goes on a first-come-first-serve basis.

    For now it's all luck, try to upgrade your device and if iTunes allows you then your UDID has been registered. I will be sending out a confirmation email once I have registered all the IDs.

    Please stay patient and let me do the work.

    • Dan Steven Kuhlmann

      I hope you will not miss me :) Waiting since yesterday. Was one of the first posters here but didn't got an email and cannot upgrade.
      iTunes says the firmware is not compatible with my iphone :(

      • Dan Steven Kuhlmann

        And of course as I already sad: its a really great job you do for us! Many many thanks!

      • http://www.sizlopedia.com Saad Hamid

        If you are among the first 100 who posted. I think the device has been registered for you. Now working on the registration of others. Enjoy!

      • wilsonchu

      I am like keep waiting … I am checking my inbox every one hour.. I have already submitted my UDID but still not registered. I am sorry to ask you but I am from Oman and I've tried to register it legally in store but returned back with error as this country is not supported. So what should I do now ??Please register my UDID I'll be very thankful to you.

    • Beedle

      thats not true, i read this so i tried to update it, and itunes let me. but i cant use it anymore :´( please edit your post so that noone else does this :(

      • sureshdahal

        May be you tried with shift+restore which will allow you to restore but the phone gets bricked if you don't have ur UDID registered. You should have tried with Update button which won't let you to restore the 4.0 if u donot have ur UDID registered.

      • Beedle

        nope, i used update, but does it make a difference if i did it on a mac or pc?

    • sureshdahal

      Oh ! please saad ! Give me the reply..

    “” that means if every one send you 5pounds you will recive in a view hours something more than 3.000 pounds.. damn shit “”

  • denlesko

    Can't wait to get my UDID activated and supper excited about multitasking! OMG i am supper thrilled to play with it on my phone! :)

  • http://www.sizlopedia.com Saad Hamid

    Even if I charged $2 for each registration, I would have made $1000 by now =) but doing this for free. Unfortunately! the slots are limited but I am bringing in more developers.

    It's free for all so have fun.

  • Dan Kuhlmann

    I was the 31th who posted down here but are still not able to upgrade.

    iTunes says that my iPhone is not compatible :(
    Sorry for my posts but I am so excited to upgrade and to play with 4.0 because I have 2 days off now :)

    • Sahil Arora

      Do you have iTunes 9.1?

      • Dan Kuhlmann

        Yes.. newest iTunes version via software update…

      • Sahil Arora

        I think you have to do it through a restore. hold option and click on the restore button. Then click on the firmware. The restore method should work just fine

        @ Sahil Arora: Thats the way I tried it all the time. Restore that I browse the Firmware, klicking OK and it says that the FW is not compatible with my iPhone (I loaded the 4.0 from the link here at sizlopedia yesterday for my iPhone 3GS (the exact name is: iPhone2,1_4.0_8A230m_Restore.ipsw)

      • Sahil Arora

        O I tried it and it worked for me. So im not too sure then

      • Dan Kuhlmann

        The problem is that I do not know if this message is coming when my UDID isnt registrated or if it is another problem?
        So if somebody can say: yes, your UDID is registrated that I can look over to solve this problem…

        But I dont know anything now :( Have to go to bed now. Hope tomorrow it will work :(

      • Dan Kuhlmann

        No way… it doesn't work :(

  • Matthew_W

    My favorite new feature will be MULTITASKING. It is the last feature left that Apple needed to add that “uncripples” the device from Android and other platforms, such as RIM. Apple now joins the party! I cannot wait.

  • Timothy K

    Hey, I like the background support and folders. Multitasking would be my favourite but I'm stuck on a 3g for now!

    • Derek

      I agree multitasking is the best feature of the 4.0 firmware

  • wilt0000

    do you have to pay

  • leemcrobbie

    There is two great new features folders :) and multitasking both improving efficiency and ease of use :D cant wait to see if i get in the beta :)

  • jonathanclulow

    Hello.
    I hope you can still register my UDID I sent you.

    I understand I am late to join this but if you can make it possible I owe you a favour.

    looking forward mostly to folders I think. Really tidy up the iphone. I try to do the same thing with pages so it'll be really useful.

    Also looking forward to multitasking of course.

    To be honest the whole update excites me.

  • justinvins

    i did that thing where i payed 5 pounds which was 2 and a half hours ago (even though they said it would be done in 15 minutes) and im still getting error message 13 from itunes… i also tried on my mac and it gets stuck on “preparing iphone for restore”… does anyone have any ideas? i need 4.0!!

    • David Lim

      You might've gotten scammed out of 5 pounds. I replied to this developer's email stating that Saad Hamid said this was a free service of his. Saad, thank you very much for your service! People should not feel to be entitled to a UDID registration so stop whining, remember this is a free service!

      • justinvins

        yea i figured it might be a scam but i thought there might be some chance that it could actually be legit so i figured it would be worth the try. i hope i get my UDID registered!

  • Matthew

    My favorite feature of iPhone OS 4.0 is multitasking! This is going to be soo cool!

    #1 tentpole feature, multitasking

  • rhey

    One of the best new features I like is of course the multitasking… Other notable ones are the option to change the background and create folders. Good job on these freebies!

  • thomasclayton

    My favorite is folder's, SPELL CHECK(:, IBooks (I was really hoping that they would add this, AND THEY DID(: ) and I can't use multitasking since im on 3g): but other than that I like the unified inbox.

    multitasking makes everything easier, and everything updated :) and folders, we could do things conveniently without having to scroll so much pages.. :)

  • Rick

    definitely Multitasking- extremely important

  • Marko

    Feature #1 – Multitasking is the best and most needed feature. Now i can listen to pandora and write emails at the same time :)

  • Cam

    Definitely looking forward to folders.. but the Enhanced mail will also make my life much easier.

  • Yanosz

    Easily the best feature of the new OS is the ability to multitask. I don't think people understand how huge this is until they have actually used it.

    I hope you're still giving out UDID!

  • tudorniculaescu

    The feature prefered by me of the 7 tentpole it's 'digital zoom' and 'tap to focus on video rec'

    Thanks

  • edward a

    very excited hehe

    -Ed

  • edward a

    tentpole number 1 bc the background running is such a great improvement and just have really been waiting for this. it is going to make the iPhone so much better. glade it does nothing to performance and battery life too.

  • andbert

    I would say the “All in one” email inbox. For me, that is invaluable!

  • tschoss

  • Michael Taylor

    I would have to say that folders is my favourite feature of the seven although multitasking is a welcome (if late) addition i cannot use it as i have a iPod Touch 2g. iAd is also a favoured feature for me, i hate adverts i games or apps that take you away from that app or constantly pop up until you click them.

  • Cauê Leme

    my favourite is Multitask

  • shipmaster117

    all the features of it are great

  • Matthew Liu

    I'm eager to discover all the new features of the iphone os 4.0!Specially the multitasking!!!This is the best one ever!Hope i'll get the chance to test that, been waiting for so long.

  • leonardocalmon

  • tsokhey

    I like the idea of multi-tasking, would really appreciate being able to test this.

  • itsjif

    hey, i'm not to sure how to go about this.. i've sent in my name with email and my UDID, but I havent recieved any sort of conformation, and i really dont want to go ahead and install 4.0 and brick my iphone… and is anyone sure that doing a forced restore (shift+tab..select 3.1.3 again etc) will definetly resotre the phone back to 3.1.3?
    Thanks =)

  • Toad Walker

    Definantly GAME CENTER!!!!! WOOT FTW

  • DS

    so i filled in the form for the UDID and waited for a few days and of course bricked my phone meanwhile… well i thought i'd install 4.0 OS since promised time was just two hours… riiiiiight… anyway you can congratulate me with becoming an iPhone developer since i had to pay $99 for apple developer program to un-brick my phone.. stupid me but i kinda liked to pay for my mistake this time LOL GOOD LUCK TO THE REST who are waiting for their UDID added…

    • itsjif

      lots of people have had the same problem, and are reporting they were able to force restore their phones back to 3.1.3 etc.

  • Jackson

    MULTITASKING!

  • john

    i most interested in the multitasking. thanks for the activatoin

  • Brad Gough

    Multi Tasking and folders – just like everyone else

    Thanks in advance

    • Brad Gough

      I've tried to upgrade to 4.0 several times in the the past 2 days. I've tried as Brad Gough, and goughbradley. I have been up to 4.0 only to see the 'you're not an iphone developer' and so I've had to go and downgrade to 3.1.3 (found a really simple guide online). I'm trying this one more time. My favourite new feature will be Multi-tasking (love internet radio) and folders (wanna be organized).

      My UDID is: b3856ca46ed244e5621f37f659ca575b4547a41c

      I've filled out the form, but I'm going to fill it out again as Brad Gough, with my e-mail. If this works – thank you VERY MUCH. If not, I guess I'll just have to wait like the rest of the world ;)

  • stephenjeffrey

    Multitasking and folders is what I'm after. These are the two main reasons why people jailbreak their iPhones. I won't to see what all the fuss is about

  • zaccammaz

    the new multitasking feature would have to be my favourite. It's about time apple got practical.

  • Lennart Korf

    Folders is my favorite.

  • kclubb

    would have to say multi-tasking is the best option for me. I have missed this (the only thing) that my old mogul and palm pre both supported when I had sprint. Looking foward to that. Means GPS, ORB, and lots of other stuff I can have going at once.

    :D

    My favorite will be multitasking when the apps are finally out for it but until then it will be the enhanced mail app. Thanks!

  • chobi

    My favorite is ibooks.

  • Paul Shields

    Best tentpole has got to be Multitasking! Especially with the integration of background music, means I can listen to podcasts using RSSPlayer and use other apps at the same time. Sadly, no multitasking on my iPod Touch 2g but nothing a little bit of hackery couldn't fix!.

  • http://www.zachawie.blogspot.com Zach

    My favorite features is multitasking. I can't believe that you don't have to have your iPhone bunked on the charging dock just to run 2 apps at a time.

  • David Ash

    Folders is going to be a great help – really useful to finely tame all those apps!!!

  • tomer1510

    Hey!!
    the folders and the multitasking are the most amazing featuers

    • dan

  • cbuffalino

  • Mina Emsak

    Multitasking! Thanks so much!

  • christiankontis

    Totally can't wait for folders! Just added my name to the spreadsheet. Hoping for a response! thanks!

  • Mike

    Thank you so much for giving us the opportunity to try out iPhone OS 4! While everyone says their favorite is either muti-tasking or folders, I'd have to say that the new game center will be mine. As of now every game uses a different system to track stats and each one you have to sign up separately. With the new game center more games will be able to implement the same leaderboard and we can simply use our iTunes email to login which will unify all of the players.

  • http://www.sizlopedia.com Saad Hamid

    Confirmation email sent to all those who were lucky enough to get their UDID registered.

    In case you were among the unlucky ones; wait as we have a tutorial on how to install iPhone 4.0 without a registered Udid.

    Have fun!

    • LordIGR

      How i know if my UDID are unblocked? I send the form 3 days ago. But i dont receive any email. How many UDID unlock your gift away? Plis i need this, my iphone are used to my work, i am a poor developer whithout apple license. Plis help me.

    • Imhoff

      Damn that means I m stuck in recovery mode.

      • Jeff

        You can use itunes to restore 3.1.3 and after it load the firmware and “claims” that it fails, run iRecovery to set the auto-boot bit back to true.

        setenv auto-boot true
        saveenv
        reboot

        it worked for me…twice.

    • Matthew

      When will you be posting that???

    • cameronjones

      yeah when will this be posted?

    • soldier47

      Those this mean,, you wont be doing it no more??? cause I completed the procedure yesterday… Please let me know. Thanks

  • mevlutyilmaz

    My favorite is folders it is so cool

  • andybno1

    multitasking has to be my biggest fave out the 7 tentpole features

  • christiankontis

    damn. I think I was late to the party. Didn't think to search for a free way to register my UDID. Cheers to Saad Hamid for gathering the resources to do this, though. And here's to hoping I still can get put on the list!

    Thanks.

  • Mike

    I guess I didn't make the cut either, though i sent mine earlier. Ah well, thanks anyway.

  • Manuel

    MUltitask!!!!!!!

  • SuBReH

    Sorry, I never used the same name (probably why I didn't get an email). My name is Subhan Rehman and once again my favourite is multi-tasking.

    • Subhan Rehmansub

      Damn, well thanks anyway

  • Zeke Ortiz

    anyones been registerd yet? mine hasn't and i have been wait for 24 hours

    but anyways my favorite feature is multitasking

    YAY!!

  • ari3ngr

    I believe ibooks is one interesting app for every user because even it will probably be difficult to read from the iphone you will still be able to have access to books you like and you will be able to read any part you want straight to your phone. Thats magic.

  • Phil M

    My favorite is probably the iAd. It would make more devs interested and result in a wider range of apps and they would free.

    Thanks for the opportunity.

  • mafiaman1234

    my favorite thing about iphone os 4.0 is the unified inbox. I have several email accounts and I just hate switching back and forth. So this willhelp me to save time

  • kyleD

    folders will make my phone more organized!

  • zehara

    i cant wait to test out the folders my home screen is a clutter.

  • vincentjohn

    Most definitely Multitasking. Since getting my iPod Touch in December last year, it has been the feature that I've wanted the most considering the vast array of things that I do with it. I browse the internet, check my email, synchronize my lecture notes (using Dropbox), converse with group members (via Skype), read books (via Stanza), remind myself of project due dates (via Calendar), play the many free games available in the App Store and listen to music.

  • JoshB

    My favorite feature will definitely be folders. They will be so useful! I finally would have to have 6-8 pages of apps! (Multitasking and the others will be cool also.) Thanks guys!

  • JoshBryant

  • mattlewis

    Hi :)

  • michaelbilik

    Hello,
    my favourite feature is multitasking!
    Backgrounder often crashes when used with bigger apps like Navigon and I have to put in the hole adress in once again. Hope Apple`s Multitasking will do a better job, can`t wait to test it!

  • keahyu

    Looks like the multitasking will come in handy, but I'll settle for the folders as my favorite cos it'll definitely help clean up the screens. Thanks for the UDID. Hopefully the next gen iPhone won't be too spectacular. Otherwise, it'll really be a bummer for me as I just got my iPhone 3gs not that long ago. Thanks anyway. Much appreciated.

    Hi

    My favourite tentpole by far is the unified inbox, as a user with numerous email accounts (personal, work, uni, mobileme) a unified inbox will make it so much easier to manage my incoming mail.

    It would be Multitasking, but I have the iPod Touch 2G and he has a lock of support for this feature, so it's definetly Folders. I love how Apple made that UI soo good looking :) ))

  • Danijel Grabovac

    I like the idea of the game center, but I am really looking forward to multitasking. BTW, I applied as Hooly, but the name was taken on the website.

  • Fred

    Can't wait to test the multi-task feature. This one is also a major must have for the Ipad compared to competitors. Thanks for sharing you developer account for testing de new 4.0.

  • Tramber29

    Thanks you.
    My favorite is the Unified Inbox. i'm looking forward to using it.

  • Elijah Tuttle

    I think gaming zone would be awesome, a portable Xbox live.perfect for if you're bored and have WiFi.
    Hope i'm not too late.

  • a33a

    What can I say?
    I would say I'm anticipating MultiTasking however that will not run on my iPod Touch 2G.(meh, I can use ProSwitcher etc. for that) So I will have to say folders. Watching the keynote , I did quite admire Apple's implementation of folders.
    Thus my favourite feature of iPhone OS 4.0 is , the folders.
    iAd is probably better than AdMob and the Game Centre looks interesting.
    Enterprise is irrelevant to me however.
    The unified Inbox is perhaps a good feature for me. It will make organisation alot easier.
    Anyway,
    Thank you for registering my UDID and have a nice day ;)

  • Jonathan

    Hi,

    I would say that multitasking was one of the most important thing that we need to have. Example when you're playing games and suddenly a call comes out.. Pooooff.. Your games exit. So.. Multitasking will be the best thing!. I'll be waiting for the UDID thanks a million.

    Definitely iBooks… I never ran into the app limit, so folders isn't really necessary, multitasking isn't available on the iphone 3G and I'm not an enterprise user… But I do have several books-apps on my iphone allready; having one unified ibooks app is really what I needed.

  • crbsfx

    I prefer multitasking

  • Tijl Deneut

    I would definitly say folders and unified inbox. My 3GS allready has multitasking doesn't it?

  • closequarters

    Folders is probably my favorite feature, now the home screen wont be so cluttered for me :)

  • henstudio

    Multi tasking, my favorite, and i just cant wait to have it!

  • Christopher Fuchs

    Personally I think that multitasking is just magnificent. Not only will it work seamlessly, but they have made it so that it drains little power and processor speed. Once again Apple has done it again! When the iPad first came out, the biggest complaint was that there was no multitasking. I am glad that Apple took the advice, and will be sure to get an iPad when the 4.0 comes out for the iPad!

  • criss

    I love the new multitasking feature, I have needed it forever.

  • Kllenno

    This is SO generous of you guys!! Really appreciate your guys' hard work and helping non- developers to test drive the new firmware! You guys are frickin awesome… Love the idea of Multitasking, as it should open so many amazing possibilities for iPhone users. Also I think the springboard backgrounds should be cool! Finally Apple got the idea that some people like customization but the only way to do that was through jailbreaking. So I for one think that should be a super cool feature! Ahh I love new firmware… Once again though you guys are great and thanks for the generosity!! :D

    thank for registering my udid

    • Multitasking: It's here, finally. It's handled with a simple task switcher: double click your home button, and you get a list of running apps. Select, switch, done. Multitasking is limited to audio streaming, VoIP and GPS apps, as well as a few other allowances: they can finish specific, important tasks in the background, for example. As far as non-music/nav/VoIP apps, those can be suspended in the background, but not left running. (See below.) Full details here.

    • Fast app switching: With iPhone 4's multitasking, most apps aren't actually running in the background—just certain functions of the app, like an audio stream or a GPS lock. But! All apps can now be frozen, in full, so that when you reopen them, they're restored to exactly the state they were in when they were closed.

    • Local notifications: Notifications can be sent between apps on the phone, not just from remote servers. In other words, if something important happens in an app you've opened and moved away from, a notification will pop up in whatever app you're using at the time, effectively saying “switch back to me!” It's a fairly clever way to keep track of multiple apps without the need for a start bar or dock-type interface. From Apple's dev guidelines:
    n some more etc…!
    hey,,plz..

    My favorite feature Apple has decided to finally to implement into the operating system is the multitasking features. Finally! Now like us, the iphone is capable of doing more things than once. This should really add a ton of functionality and convenience to the iPhone's intuitive UI.

  • Alexandros Ioannidis

    i suppose the best feature will be the multitasking, cause it will be installed by default, not as a 3rd part app.

    For me it's a toss-up between the multitasking and the folders but I would have to say the folders will be the most useful part.
    Hopefully I'm not too late to get the activation. I am really looking forward to try this thing out. Thank you.

    • Hamu Sydney

      ****UPDATE****
      Just had a look at my mates iPhone 3GS on 4.0 (his UDID has been registered), but have to say that Multitasking is not that great on 4.0. I know that this is BETA firmware, but it seem really buggy / laggy / not the greatest…. lol……
      I did however like the look of the folders – and accordingly will change my main feature for testing to Folders.
      Cheers.

    Folders because now you can organize apps and have the ability to put more apps on your iPhone and Wallpaper because you can finally customize your boring home screen

  • Steven

    I think folders is cool, But multi tasking is my favorite feature. The Ad thing seems like it will be more annoying then the way developers have ads already. I think that it’s funny how most of these features have been available to people who have jailbroken devices for over a year, Mabe Apple is finally giving in.

  • lazier111

    Multitasking is one of the add-on that i like the most…I believe most of the people will feel that too…

    Multiple Exchange accounts is going to be incredibly beneficial! And, of course multitasking. I have several applications I am constantly switching between but being able to simultaneously run them at the same time will be a lot less time consuming. I am very eager to try this out!

    My favorite feature is multitasking, and second is folders. I also like how you don't have to jailbreak it or run a very old firmware to have a reflective dock now!

    Haha, I never read the instruction to post here!!!! Oh and I think I accidentally put mine in as an iPhone 3Gs, I forgot to select that, and it's default. I resubmitted mine as an iPod touch 2G, which is what mine is. Please please PLEASE register my UUID, because this is really exciting to me! It is also way easier than opening up the firmware file, which I tried and failed at ^_^

    I'm looking forward to the folders feature the most, i was getting a little tired of having to delete my apps because i can't have more than 11 pages of apps on my device (i have close to 20 pages of fave apps i want on my device) so this feature should be good if it lets me add more apps :D … i also want to see what can be done with the whole gaming network with game centre :D

  • Steven Jackson

    Big one for me has got to be Folders, it's going to make accessing stuff so much easier. It looks clever the way it automatically names the folder based on the type of App it contains, but what if I mix different types of App in the same folder

  • Mahdi Mafi

    Folders :)
