Few hours ago the famous jailbreaker and hacker iH8sn0w has tweeted and claimed that he has found a loophole in Apple’s apticket system and he has restored iPad 2 to 5.0.1 from iOS 5.1. So it is also assumed that he has found the way to downgrade iOS 5.1 to iOS 5.0.1 on all A5 devices. He also mentions on followup tweets that A5X devices i.e iPad 3 will also be able to work once Apple pushes new firmware for them. This is a good news for people who are willing to find solution for downgrading their A5 and A5X devices i.e. iPhone 4S, iPad 2 and iPad3.

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