For those iPhone 4S, iPad 2 and iPad 3 users who have been waiting anxiously to downgrade their device’s iOS firmware are certainly in for a treat by the iPhone Dev Team. iOS hacker MuscleNerd has indicated in his recent tweet that the next Redsn0w will have the feature to downgrade iPhone 4S, iPad 2 and iPad 3 firmwares and restore it without having to connect to iTunes. This is great news for those iPhone 4S and iPad 2 users who are on iOS 5.1 and above and wish to get Untethered jailbreak on iOS 5.0.1.
The Redsn0w now already has the feature to downgrade A4 devices namely the iPhone 4, iPhone 3GS, iPad 1 and iPod touch to lower firmware versions and also save the SHSH blobs and APTicket. However it is still mandatory for all A5 and A5X device users to have their SHSH blobs and APTicket for the lower iOS version saved as without it obviously the Redsn0w will not be able to perform the downgrade.
If you had Untethered Jailbreak for your iPhone 4S or iPad 2 when you were on iOS 5.0.1 than most probably Cydia has already backed it up for you and there will not be any problem. For those users who do not have the shsh blob saved and also have never given Jailbreak will not be able to use the downgrade feature.
The upcoming Redsn0w 0.9.11b1 will have new set of features in Extras -> Even More-> Restore i.e of Local Restore and Remote Restore. Local restore will look for shsh blob files in your computer while Remote option will look in Cydia once you have entered your device in DFU Mode.
There is however no ETA available but we expect the new Redsn0w to be released within days as the iPhone Dev Team is really quick in delivering updates.
