iOS 4.3.1 Untethered Jailbreak in Beta Stage by iPhone Dev Team

After showing off his iPod being jailbroken on iOS 4.3.1, the iPhone security expert Seten Esser yesterday tweeted that the has been handed over to iPhone-Dev Team who are currently testing it in its beta stages and maybe out anytime soon after its successful testing on their Redsnow or PwnageTool.

@i0n1c: The iPhone-Dev-Team is already beta testing the untether. So it is up to them to give you your tool of choice.
@i0n1c: Please don't bother the Dev-Team now. The deal is: if the beta test is successful, they are free to do whatever they want with it.
