iPhone Dev Team Releases Unofficial PwnageTool Bundle For iPhone 3GS


Jailbreak iOS 4 on iPhone 3GS

iPhone Dev Team has released an unofficial PwnageTool bundle for iPhone 3GS owners with the old bootrom that want to update to iOS 4.2.1 without upgrading their baseband.

So if your iPhone 3GS baseband is 05.13.04 or lower (Settings -> General -> About -> Modem Firmware) then you should install the bundle before using PwnageTool 4.1.3 to update to iOS 4.2.1

This gives you best of both worlds, you update your iPhone 3GS to iOS 4.2.1 and since the baseband is preserved, you can unlock your iPhone 3GS using Ultrasn0w 1.2 without the need to update it’s baseband to 06.15.00, which has its risks.

iPhone Dev team has provided the following information on their blog about the unofficial PwnageTool bundle:

  • Navigate to Contents/Resources/FirmwareBundles/.
  • Copy and paste the iPhone2,1_4.2.1_8C148a.bundle that your had extracted earlier into the FirmwareBundles folder.

That’s all. When you launch the PwnageTool, it will pick up the latest firmware bundle. You can then use it to upd

As always, let us know how it goes.
