    does this really work?

  • paul June 25, 2009, 9:07 am

    i have an Iphone 3G running 3.0 never been hacked/jailbreaked.
    can i jailbreak it using redsnow as you stated and then just installing ultrasnow? because i read in the bottom it only suitable for phones that been unlocked with yellowsnow but again ive never done anything to my phone besides the apple updates. i have everything ready but i just wanna make sure it could be done before i start because i dont wanna ruin my phone. i really dont think i could live with out it.

    Thank You.

      Hello! I have jailbroken my iphone 3g, apparently. But I cannot do the cydia part, unlocking. Dont you need an internet access to do it? And how could you do it without a working unlocked simcard to get you online…?

      How can you
      Run Cydia to install Ultrasnow without the simcard being unlocked

      bro it all a con dev team work with apple to stuff people around ask yourself this why do you have to pay for the lateset release of redsnow(ulrasnow). All the torrents except 1 don't work and the 1 that does is encrpted and the site you are supposed to get the password from is a bogus site as it will ask for you phone number then spam sms messages at $3.50 per message and you will still not get the password . You bought a iphone i think that is real funny. Welcome to the world of rip off(apple). Whant more proof your being riped off All Apple computers have intel cpu, nvida graphic cards and yet you pay 2x the price for all there computers . Save yourself money bro buy nokia phones and build yourself a computer and run windows hell you don't even need to buy windows there are plenty of hacked versions on the net trust me i have latest softwhere from microsoft and for last 10 years have not had to pay for any off it and they all work ok even pass microsoft genuine advantage . Appl are great at ripping people off they have been doing it for 20 years now . They would not have changed to intel chips if there hardwhere was so good just now they make more money as the con is better now .good luck

    Thanks Saad for the efforts to put up these tutorials, i really appreciate your hard work.
    But i have a question to make;

    I was reading one of your recent blog post here http://www.sizlopedia.com/2009/10/19/hacktivate… and there you said we have to follow from instruction 3 to unlock 3gs, but here on this post at the end you said “And the method is not recommended to unlock an iPhone 3GS.”, please make it clear as i have done the upgrading thing and now stuck with on how to unlock it, i'm on 3.1.2 now !

    waiting for your reply


  • Cena December 15, 2009, 10:34 pm

    Sorry I am a little confused, is it ffee to download it or costs money?

  • Glen January 7, 2010, 9:52 pm

    typical you have to by the latest version of ultrasnow (resnow ) then apple release a new version as update then dev team release a new version which you have to pay and on and on it goes when are you alll going to relies that dev team work with apple .Like all things apple they try to rip you off . Ask yourself this why do you have to buy the latest verison of redsnow(ultrasnow) but all the older copys are still on the net …….TO RIP YOU OFF
