Downgrade iOS 6 To iOS 5.1.1 iPhone 4S: We get Messages & Emails every day asking about Downgrade iOS 6 to iOS 5.1.1 on iPhone 4S and when it will be ready to launch for the iPhone 4S.
A few months back we released a redsn0w feature that lets you downgrade A5+ devices from 5.1.1 to anything lower (if you had saved blobs). Unfortunately once the 5.1.1 window closes, redsn0w’s 5.x downgrade feature will no longer work. Most A5+ users will not be able to downgrade. So if you’re an A5+ owner up at 6.0 when the 5.1.1 window closes, you’ll be stuck there without a jailbreak for now.
