The iPhone Dev-Team has updated RedSn0w to jailbreak the iPhone 4S and iPad 2 on iOS 5.0.1. This latest update includes the corona-A5 jailbreak (used in Absinthe), it can easily reinstall untethers (if you accidentally manage to uninstall it), it grabs SHSH blobs directly from Cydia (but it still won’t help for the iPhone 4S or iPad 2), and provides more useful diagnostic information about your phone (vulnerable basebands, exploitable bootroms).
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.)
While this update does not provide anything that you couldn’t manage to do before its release, it’s a handy feature update for the versatile jailbreaking tool. Be aware that this update does not include a jailbreak for iOS 5.1 for A5 devices, and it won’t help you restore an iPhone 4S or iPad 2 to iOS 5.0.1. A feature slated for addition in the next version of RedSn0w is built-in restore support, which will be handy in the event that iTunes stops restoring jailbroken phones.
