As guessed earlier, the U.S. carrier Sprint has officially announced the HTC Touch Diamond and the HTC Touch Diamond Pro at CTIA today. The first will be available before the end of September (word has it around the 14th.) for $249.99 on a two-year contract, while the latter (complete with slider keypad) will cost you an extra $50 and will be out on October 19th. This beauty is running Windows Mobile 6.1, has a 3.2 megapixel camera, 4 GB of internal storage memory, and a smooth touch interface. We’ve been enjoying the HTC Touch Diamond up north via Telus for a little while now, so it’s good to see our southerly neighbours getting some CDMA-flavoured love too. For specs, hit up HTC, and for sales info, check out Sprint.
