HTC may be amping up for its big debut of the first cell phone to use Google's android platform later this year, but let's set that aside right now. Why? Because HTC is unleashing its sleek and sexy Touch Diamond on US territory — Sprint territory to be exact — this Thursday! It has been reported that the phone will cost $299 on a two-year contract or $549 if you buy it outright. To jog your memories a bit, the Touch Diamond is the elegant, visually stunning little phone I checked out in London this past May.
