Did you recently update to iOS 5.1, only to realize that there isn’t yet an untethered jailbreak for Apple’s latest firmware? Good news – there’s a loophole for that! According to Sn0wBreeze creator iH8sn0w, it’s now possible to downgrade the iPhone 4S and iPad 2 from iOS 5.1 back to 5.0.1.
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 pretty significant for anyone that’s already updated to iOS 5.1. While a loophole has been discovered, however, no public tool or instructions have yet been released to help users downgrade their devices, although it is likely that such a tool will be released in the near future.
