iH8Sn0w, the hacker behind Sn0wBreeze, iFaith, iREB and other popular jailbreak related tools has discovered a loophole in Apple’s apticket system that allows you to downgrade your iPad 2 and iPhone 4S iOS 5.1 to iOS 5.0.1 firmware.
The loophole found by iH8Sn0w, in Apple’s apticket system will even work on A5X devices as soon as Apple pushes a new firmware update. This downgrade method will work on all A5 and A5X devices which includes iPhone 4S, iPad 2 and the new iPad 3.
This is what iH8Sn0w has tweeted about the apticket system loophole and 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.

This is a big news for the jailbreak community because at this time finding jailbreak exploits for every iOS update has become a difficult task and it is nearly impossible to downgrade iPhone 4S, iPad 2 and iPad 3 because of the aptickets system Apple had introduced in iOS 5 or later firmwares.
All those stuck with iOS 5.1 with no means of jailbreaking or downgrading back hold on tight because iH8sn0w will soon be releasing a downgrade method for your iPhone 4S, iPad 2 and iPad 3.
