We have some good news for all of you with iPad 2′s and iPhone 4S’, as you all know if you accidentally updated to iOS 5.1 there was no chance for you to downgrade to iOS 5.0.1 and be jailbroken. iOS 5.1 is not even tethered jailbroken for A5 devices so that means you’d have to stay without a jailbreak, but now iH8sn0w, the creator of sn0breeze, iFaith and iReb, sheds some light on everyone and tells us about his latest achievement regarding downgrading.

Found a loophole in Apple’s apticket system. Restored my iPad 2 to 5.0.1 from 5.1. Works on all A5 devices.

A5X devices will work too once Apple pushes a new firmware for it.

BTW, This cannot be applied to basebands. Only iOS itself.

As of now you can only downgrade iPhone 3GS’, iPhone 4′s and iPad 1′s to iOs 5.0.1 and that to by using the SHSH blobs saved by TinyUmbrella or TinyCFW.

With this discovery it means that the iPhone 4S and the iPad 2 (powered by A5 chip) and the new iPad (powered by the A5X chip) will be able to downgrade to previous iOS versions for a stable untethered jailbreak, till the untethered jailbreak for iOS 5.1 is not released. This is a very big achievement as Apple had made it very difficult to downgrade to previous iOS versions.

As of now I believe you will need to have the SHSH blobs to downgrade to 5.0.1.

iH8sn0w has said that he will not shed any more light on this matter and will keep it confidential until he completes all his tests.

Are you one of those who accidentally updated to the worthless iOS 5.1?
