on October 3, 2009

Follow the steps below to Jailbreak and then Unlock your iPhone 3GS on Firmware 3.1 without having to update the baseband. Please proceed at your own risk.

Another important note is to remember that the method only works for those who already have a previously-Jailbroken iPhone 3GS on an old firmware. Users with Out-of-the-box device shouldn't waste their time with this tutorial.

Please backup with iTunes before trying this. Here is how it goes:

  1. Grab and download the Pwnage Tool 3.1.3 for Mac OS X (At thePirateBay | Alternate)
  2. Make sure to update to the latest iTunes 9 before attempting this unlock.
  3. Download the 3.1 Firmware for iPhone 3GS and save it on your desktop.
  4. Run the Pwnage Tool 3.1.3 and select iPhone 3GS and click next.
  5. Select the Firmware 3.1 with build iPhone2,1_3.1_7C144 and click next.
  6. Select 'Yes', click next and then select 'No', now the 'Building IPSW' has started.
  7. Once completed, select 'Yes' to the prompt and click next.
  8. Open iTunes and click Restore (while holding Option key) and select the newly created Custom 3.1 IPSW on desktop.

Voila! the iPhone 3GS has now been successfully updated to 3.1 Firmware while preserving the baseband, now follow the steps on this article (starting from step-3) to unlock it with Ultrasnow.

Here is a direct link to download the iPhone 3.1 Firmware for iPhone 3G.

Note: This method will only and only work for the iPhone 3GS. Also please note that at no point are you supposed to 'Update' to a newer firmware in iTunes, only use 'Restore'. The method we used follows the Simple mode in PwnageTool 3.1.3.

Update: Custom/Hacktivated IPSW for iPhone 3GS users on Windows is now available.

    Hi

    I don't understand when you say “the method only works for those who already have a previously-Jailbroken iPhone 3GS”. I originally jailbroke my 3GS when I had 3.0.1 I then “restored” it with the new 3.1 software through iTunes. Therefore I lost my jailbreak. Can I use this tool to jailbreak my 3GS again? Or does my phone have to be ALREADY jailbroken?

    Thanks

      That sentence basically means that your iPhone 3GS shouldn't be one with 3.1 out of the box. Since your iPhone 3GS had been Jailbroken once in the past, I guess you are safe to try this procedure.

      Proceed with caution please.

        TUAW.com confirmed that if you have updated to 3.1 via iTunes, this tool WILL NOT work. I have to wait until a new redsn0w comes out.

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

      That's normal. It's a bug in the new OS published by Apple.

      • speedbratz

        so does it happen only with jailbroken iphones or even the ones that are right of the box
