I have updated the initial post to keep it factually correct, but please note, nothing has changed regarding the satus of the iPad2 jailbreak. It remains 4.3.3 or nothing. It is simply that iPad2 3G GSM owners who have saved blobs are now able to restore that firmware using TinyCFW or redsn0w 0.9.9b9 and TinyUmbrella, wheras they were previously unable to.
