With Apple having released iOS 5.1.1 to the end-user in the last couple of days, the various dev teams have been hard at work in updating their respective jailbreak tools to recognize the latest iteration of the Cupertino’s mobile OS.
None have been more dogmatic in their approach than the iPhone Dev Team, and as per MuscleNerd via Twitter, the latest version of Redsn0w will include downgrade capabilities for the very newest additions to the iDevice roster.
Although many will have happily updated, there are many reasons why you may wish to revert back, and since Apple doesn’t allow this to happen, we rely on the likes of the iPhone Dev Team to provide us with the solution.
Having already enabled A4 devices to be downgraded, the Redsn0w tool is now being brought up to speed to allow those wielding an iPad 2/3 or iPhone 4S to downgrade their software back to an earlier version – providing, of course, that SHSH blobs and APTicket have been stored away in a safe place.
If you’re unfamiliar with SHSH blobs and whatnot, there is a chance Cydia may have backed them up for you, so even if you don’t think you’ll be able to downgrade, it’s certainly worth keeping an eye out for.
There are many reasons why you may wish to downgrade, and although the latest iPad is yet to be exploited (not strictly true, but i0n1c isn’t the sharing kind), those running an iPad 2 or iPhone 4S can still enjoy that untethered jailbreak via Absinthe by reverting to iOS 5.0.1 or earlier. Currently the only iOS 5 jailbreak for those devices, although the various hackers are looking for holes in these newer iterations of iOS 5, one suspects that, with interests shifting towards iOS 6, they may hang onto any significant discoveries in favor of increasing the chances of a swift and successful jailbreak of the future firmware.
The new version of Redsn0w is yet to be released, and until the iPhone Dev Team release further info, the ETA is anybody’s guess. Given the group’s track record in these types of situations, we don’t expect to be waiting round too long, so while it’s nothing more than a guesstimation, expect the updated Redsn0w to drop very soon.
