At last, the HTC S743, that is, the US-variant of the HTC S740, has arrived. In this video we unbox the sleek and sexy dual-keypad Windows Mobile Standard device. It brings several of the features that you’ll find on devices like Touch Pro and Diamond, but in a smaller, non-touchscreen, and less expensive version.

The HTC S743 is an unlocked GSM device (so it’ll work with HSDPA on AT&T and EDGE on T-Mobile) from eXpansys for $489. It’s running with a 528MHz CPU, 256MB ROM and RAM, a 2.4″ QVGA screen, plus WiFi and aGPS. To see more specs, check out PDAdb.net.
