Though many versions of the Touch Pro2 have been updated from WinMo 6.1 to 6.5 over the last half a year, theTilt2 -- AT&T's version -- has been so far left out in the cold. That still hasn't changed in any official capacity, but a new branded ROM leak seems to change all that, giving us hope that a formal release is finally in the cards (some four months after Sprint, for the record). At a quick glance, WMExperts says that the leak is running Sense 2.5 and feels more responsive, which is always a good sign -- and considering that Windows Phone 7could very well be out by the time AT&T outs this on its own for all we know, you might want to strongly consider pulling the trigger upgrading to this early release.
