Hacker Comex mentioned in his tweet about the bugs fixed/going to be fixed in JailBreak Me 3.0.

The upcoming jailbreak for iPad 2 named JailBreak Me 3.0 for iOS 4.3.3 by Comex will be released soon and as he mentioned, without bugs. We should hope that comex also released the Jailbreak for firmware older than iOS 4.3.3.
