Last month we had reported about the release of the iOS 5.0.1 for iPhone, iPad and iPod touch. While the iPhone Dev Team had immediately updated the Redsn0w tool to apply tethered jailbreak to iOS 5.0.1 it couldn’t be unlocked using the Ultras0w tool as it was not compatible with the iOS 5.0.1 firmware.
However we now have the Ultras0w Fixer which is compatible with iOS 5.0.1 firmware and can be used to unlock iPhone 3GS and iPhone 4 running on iOS 5.0.1. The release has not been made by the iPhone Dev Team and hence the updated Ultrasn0w is yet not available.
To Unlock your iOS 5.0.1 device you will first have to Jailbreak it. Currently users can only rely on Sn0wbreeze tool as it is the only tool which that supports unlockable baseband preservation on iOS 5.0.1. The latest Redsn0w cannot be used for baseband preservation and hence there is no point in using it.
Ultrasn0w fixer will unlock iOS 5.0.1 on iPhone 3GS or iPhone 4 that have the following unlockable basebands:
How To Unlock iOS 5.0.1 Using Ultrasn0w Fixer:
Step 1 : Launch Cydia and navigate to Manage followed by Sources.
Step 2 : Tap on Edit followed by Add. Now enter the link http://cydia.myrepospace.com/smolk/ and than tap on Add Source.
Step 3 : Once the source is installed just tap on it to enter in and you will see two versions of Ultrasn0w Fixer, one for iPhone 3GS and the other for iPhone 4.
Step 5 : Install the relevant package and reboot your device after its done.
That’s it. If you have followed all the above steps successfully you have unlocked you iOS 5.0.1 based iPhone 3GS and iPhone 4. Although the Ultrasn0w which will be released by the iPhone Dev Team will be much more stable but we have not yet received reports about any bug from this tool.
