Re-Restore or Downgrade iPhone, iPad iOS to iOS 5.1.1using new Redsn0w [iOS 6 Jailbreak Possibilities]
Bad news comes from hackers group known as iPhone Dev team. Musclenerd has been tweeting during an hour after public iOS 6 release. He provided us with all essential info regarding iOS 6 jailbreak and its possibilities. You need to re-restore or downgrade iPhone or other iDevice running iOS 6. The bad news is that we will not see any jailbreaking solution for newest Apple iOS nearest time.
So if you are using iPhone on iOS 5.1.1 you better to save your 5.1.1 blobs because Apple will close SHSH blob signing window soon! So hurry up! Also iPhone 4S, iPad 2 and iPad 3 users are stucked on iOS 6 and there is no way to jailbreak it. So let’s take a look at possibilities to jailbreak 6 version of iOS usinf re-restore or downgrade.
iOS 6 Jailbreak Possibilities:
A4 devices and iPhone 3GS will always be downgradable (and jailbreakable) due to limera1n exploit. The tethered iOS6 jailbreak for those devices (and untethered for old-bootrom 3GS) will be out when Cydia and other important pieces are all working properly
iPad2 owners who have both 4.x blobs and 5.x blobs will always be able to downgrade to those versions, even once you come up to 6.0 and the 5.1.1 window closes (don’t do that yet though!). You need both 4.x and 5.x blobs to qualify for the downgrade even if you only wish to downgrade to 5.x
iPad3, iPhone 4S (and iPad2 owners who don’t satisfy #2) will always be able to RE-restore the current 5.x OS that’s already on their device. So if you’re at 5.1.1 when the window closes (and you’ve saved your blobs), you’ll always be able to RE-restore to 5.1.1 again. This makes the 5.1.1 jailbreak a lot less fragile — you don’t have to worry about messing up your install with funky extensions or getting into a boot loop, because you can always RE-restore from 5.1.1 to 5.1.1 again (or from 5.0.1 to 5.0.1 again, etc). But once you fall off the 5.x train by restoring to 6.x, you’ll be stuck there until the next jailbreak. The only one good thing in it that all iPad 3 and iPhone 4S users will get complete set of iOS 6 features and other novelties in latest iOS from Cupertino company.
NOTE: Please be aware that RE-restores and also iPad2 downgraded iDevices will always update latest baseband (not the one that came with that firmware). So don’t use any of this if your iPad 2 iOS 6 unlock depends on the current baseband version.
Famous Dev Team promises all of these features to be released very shortly in a new version of redsn0w jailbreak. For now just be sure you have saved your iOS 5.1.1 SHSH blobs and stay away from iOS upgrade till the new iOS 6 jailbreak tool will be availible. So 5.0.1->5.0.1 RE-restores will be just as supported as 5.1.1->5.1.1 RE-restores, as long as you have the 5.0.1 blobs saved
