The team behind AlphaRevX, have just released a new Beta 2 build that brings Full Unlock, S-OFF, and Root Recovery to The Droid Incredible 2 and the Desire S. This is an updated version of the one that does the same thing for the Desire (CDMA and GSM), Wildfire, and Aria. This is beta software so be cautious, as always. Originally, the Windows version was pulled due to some bugs, but those have since been quickly fixed, and it's back up now. Hit the XDA-Developers thread below for detailed instructions. We've also included a download link for the AlphaRevX beta.
