Around last week, there happened an event on March 7 in which the world’s most powerful company released the new iPad generation which is iPad 3. With this release Apple also unleashed the latest major update of the fifth generation of its operating system which is iOS 5.1.
Since the very time the update was released, chronic dev team has came up with that tethered jailbreak for this update. Even though it is tethered jailbreak even then many users performed the jailbreak on their A4 devices.
With this tethered jailbreak here is another solution which is for unlocking your device running on iOS 5.1. The toll you will use for unlocking is ultrasn0w. Though it is not an updated version but this is a Cydia tweak named Ultrasn0w fixer which serves the purpose. You have to manually search for it as it has not been publicly released yet. In the developers repo of your Cydia you can find this tweak and this will help you unlocking your device.
Ultrasn0w fixer supports following basebands.
Now lets head towards a simple guide to unlock your A4 devices running on iOS 5.1.
