I’ve seen a few sources (namely Comex) http://twitter.com/#!/comex and it seems someone has leaked an older bugged version of his JailBreakme 3.0. It was available for awhile before it was taken down, but as you can see on his twitter account, he wasn’t too happy about someone doing that and putting him on a timeline. With all things involving JailBreaks, its best not to agitate the developers and let them work on their own schedule, unless of course if you think you can do it yourself.
According to those who did use it, it successfully JailBroke their iPad 2′s. But aside from that, there is nothing you can do with it. As Comex is not supporting this version, the best thing to do is just wait until an official version is out. Everyone got excited, but relax take a deep breathe and give it a little more time!
