Today hacker Stefan Esser has announced on his twitter profile that the Dev-Team are in the middle of beta testing the untethered jailbreak. Unfortunately no more information was given out on whether or not this jailbreak will work for the iPad 2, and of course no ETA date was mentioned for the iOS 4.3.1 untethered jailbreak. Regardless of this it is still great to know that the Dev-Team are in the middle of actually beta testing the iOS 4.3.1 untethered  jailbreak; instead of searching for a viable exploit. You can take a look at Stefan Esser’s tweet below…

My guess on an ETA, or at least a public beta test, would be this weekend. However we will all just have to sit tight for the time being and wait to see what happens. What is your personal guess of the release of the iOS 4.3.1 untethered jailbreak?
