Now iPhone Dev Team released Redsn0w update which will also install Corona Untether on your iPhone 4s or iPad 2.
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.)
Dev team has also announced that they have a plan to add built-in restore support in future version of Redsn0w, to provide an alternative to iTunes restores, which will be a killer feature as it should be able to avoid those annoying errors when you try to restore using custom iOS firmware files using iTunes.
