Official WM6.5 Leaked for Touch Diamond 2 (Topaz)
The date for the upgrade keeps coming and going, but it looks like Froidstar at XDA has gotten his/her hands on the official version, unofficially, of course.
It's an older build (2.07.58475) from July, which is evidently what HTC will be releasing to the masses. Hands-on reports are that it is very stable and fast so far.
So if you haven't rocked a custom WM6.5 update already (hard to believe) then you may want to give this a shot, or perhaps you "Chefs" need a new stable base to work from?
