This is a test version that has been out for a while, codenamed manila. From what i have read it is very very slow on almost every phone and is basically useless. The Diamond and Raphael have hardware acceleration (wheres ours?) and twice the resolution of most htc phones.
Every one is talking about the Diamond, but I'm waiting for the Raphael (Touch Pro) which is the same as the Diamond but with a slide out keyboard like our titans.
