Since the release of iOS 4.3.1 everyone has been strongly anticipating a new jailbreak. We know the iPhone Dev-Team are working diligently on a Jailbreak along with others. Recently, Stefan Esser, aka @i0n1c demonstrated an untethered iOS 4.3 jailbreak earlier on his iPad. He also uploaded a youtube video demonstrating his exploit using sn0wbreeze 2.4 on an iPod Touch 4G. Unfortunately a release date has not been made public at this time.
