Not sure what took them so long but Dev Team has finally updated their RedSn0w tool for Mac OS X and Windows which now supports iOS 5.0.1 untethered jailbreak for iPhone 4S and iPad 2. Previously, this was only possible with Chronic Dev Team’s Absinthe which supports A5 jailbreak on iOS 5.0 / 5.0.1 fully untethered. Older version of Redsn0w supported untethered iOS 5.0.1 jailbreak for A4 devices only i.e iPhone 3GS, iPhone 4 and the original iPad. But don’t get too excited as there is still no public jailbreak solution for the latest iOS 5.1, tethered or untethered for A5 devices or the new iPad.
According to the Dev Team’s official blog:
Version 0.9.10b7 of redsn0w adds a collection of useful features: It finally implements the corona-A5 jailbreak for iPhone4S and iPad2 devices still at 5.0.1. It can also re-install that jailbreak for those who accidentally uninstalled the untether. When stitching an IPSW, it can now grab your blobs directly from Cydia. It now shows a lot more info about your device (for instance, whether your iPhone3G has the vulnerable baseband boot loader, or whether your iPhone3GS has the old exploitable bootrom. (And the next new feature to be added will be built-in restore support, to provide an alternative to iTunes restores.)
