Loophole Allows Hacker To Downgrade iOS 5.1 On iPad 2

Despite Apple's policies, one intrepid iOS hacker found out a way allowing users to downgrade devices from the latest iOS versions to a previous one.

iH8sn0w, also known as Steven, revealed on his Twitter account his great discovery. He explained that he "found a loophole in Apple's apticket system."

To detail the success he also added: "Restored my iPad 2 to 5.0.1 from 5.1. Works on all A5 devices."

The Canadian based developer, iH8sn0w, is well known to the jailbreak community for releasing Sn0wbreeze, iFaith, iReb and f0recast. The success is particularly remarkable, as Apple fans might know by now that they cannot perform firmware downgrades on either the iPhone 4S or the iPad 2.

As the new iPad ships with the latest software available, iOS 5.1, it is expected that the owners will be able to downgrade to any firmware, providing that they have the relevant SHSH blobs saved.

However, iH8sn0w hasn't released additional information about the APTicket system loophole or step by step indication to help the less advanced users to downgrade their A5 Apple devices from iOS 5.1 to iOS 5.0.1.
