iOS 6.0.1 was released recently and we have already told you how you can jailbreak it using RedSn0w. While RedSn0w can jailbreak the newly release iOS 6.0.1, iPhone Dev-Team has yet to add support for iOS 6.0.1 to its popular unlocking tool UltraSn0w. However if you have upgraded your iPhone to iOS 6.0.1 and want to unlock your iPhone 3GS or iPhone 4, there’s a way to do that. In this post we will show you how you can succesfully unlock your iPhone 3GS or iPhone 4 running iOS 6.0.1 using UltraSnow fixer tool available in the Cydia for free, provided your baseband is supported.
Make sure your iPhone 4 or iPhone 3GS has one of the following basebands. You can check your device’s baseband by going into Settings > General > About > Modem Firmware.
- Baseband 01.59.00 (iPhone 4)
- Baseband 04.26.08 (iPhone 3GS)
- Baseband 05.11.07 (iPhone 3GS)
- Baseband 05.13.01 (iPhone 3GS)
- Baseband 05.12.01 (iPhone 3GS)
