Redsn0w 0.9.11b1 now allows post-iPad 2 devices to downgrade to an older firmware
Per usual, the Dev-Team whiz-kids have been hard at work trying to make your jailbroken iOS life a tad bit easier. This time around, MuscleNerd & Co. have outed their latest revision of RedSn0w (0.9.11b1), allowing folks using the new iPad, iPad 2 and iPhone 4S to downgrade to lower firmwares for jailbreaking purposes -- a feature others have been enjoying for some time now. As expected, you'd still need those saved SHSH blobs from the previous firmware in order to do so, and if your device depends on an unofficial unlock, it's recommended (with a few exceptions) to steer clear since this method will upgrade your baseband. Speaking of, the Dev-Team also notes you should stick with an earlier version of Redsn0w unless you must have the new tidbits. Those of you eager to give it a try can head over to the Dev-Tem Blog to grab yourself a copy.
