BestBuy has made the HTC Touch Diamond available for pre-order on their website for the princely sum of $699. While this is a reasonable price for sucha sophisticated device, it appears the version they are carrying is still missing the AT&T 3G bands in the 850 Mhz spectrum, meaning one would be paying $700 for a 2.5G device. I expect sales will be pretty slow.
The smartphone is expected to arrive between the 29th September to 4th October. Read more on the BestBuy website.
