Posters on various forums have been leaking like a sieve about the upcoming Sprint HTC Touch. Most recent news is that the Sprint Touch Diamond will be coming with a flat red back. Other posters report that both the Touch Diamond and Touch Pro are expected to be released with at the same time, on October 19th. That would represent a delay for the Touch Diamond of about 4 weeks, and the Touch Pro being brought forward about the same.
The Sprint Touch Diamond differs from the GSM Touch Diamond in being about 3mm thicker at 14mm and having a much larger 1350 mAh battery, vs the much smaller 900 mAh battery in the GSM device. Sprint customers are expected to benefit from the ROM improvements HTC has already implemented on their GSM device.
