A special edition of PwnageTool (version 4.1.3) has been released which can update the baseband of iPhone 3GS & 3G to 06.15.00 so that they can be unlocked using Ultrasn0w 1.2 on the latest iOS 4.2.1 or iOS 4.1 firmware. This is important because basebands 05.14.xx and 05.15.xx are currently not unlockable using Ultrasn0w.
Follow the instructions posted below to update your iPhone 3GS or 3G to 06.15.00 baseband and jailbreak it on iOS 4.1 /4.2.1.
Step 4: Start PwnageTool 4.1.3 and point it to iOS 4.2.1 / 4.1 firmware file.
Step 5: You will now be prompted to update your baseband to 06.15.00 so that it can be unlocked using Ultrasn0w 1.2.
Step 6: Now point PwnageTool 4.1.3 to iOS 3.2.2 for iPad. PwnageTool will now fetch the exploitable 06.15.00 baseband from 3.2.2 firmware and will replace it the baseband in iOS 4.2.1 / 4.1.
Step 7: Click the next arrow now to allow PwnageTool to create this custom ipsw file for you.
Step 8: Now follow the following steps to enter DFU mode:
- Hold Power and Home buttons for 10 seconds
- Now release the Power button but continue holding the Home button for 10 more seconds
- You device should now be in DFU mode
Step 9: You will now have to restore your iPhone to this custom firmware 4.2.1 / 4.1 file. Start iTunes, click on your device icon from the sidebar in iTunes. Now press and hold left “alt” button (“Shift” button on Windows) on the keyboard and then click on “Restore” (Not “Update” or “Check for Update”) button in the iTunes and then release the “Shift” button.
This will make iTunes prompt you to select the location for your custom firmware 4.2.1 / 4.1 file. Select the required custom .ipsw file and click on “Open”.
Step 10: Now sit back and enjoy as iTunes does the rest for you. This will involve a series of automated steps. Be patient at this stage and don’t do anything silly. Just wait while iTunes installs the new firmware 4.2.1 / 4.1 on your iPhone 3GS or 3G. Your iOS device screen at this point will be showing a progress bar indicating installation progress. After the installation is done, your iPhone will restart automatically and you should now have a fully jailbroken iPhone 3GS or 3G with 06.15.00 baseband.
UPDATE 1: A new fixed version of PwnageTool bundle (download here) for iPhone 3GS on iOS 4.1 has been released. Here’s how to use it:
