The first Windows Mobile 6 smartphone out the door from HTC is a winner. This phone is about the same size as the T-Mobile SDA yet it sports a side-sliding QWERTY keyboard like the HTC TyTN (Cingular 8525) and other popular Pocket PC phones. But this is a smartphone, running what's now called Windows Mobile Standard Edition. It has Bluetooth 2.0, WiFi 802.11b/g, a good 2MP camera and a QVGA display with LED backlighting that operates in both portrait and landscape modes. The S710, otherwise known by its codename, the HTC Vox, is a quad band GSM phone with EDGE that's sold unlocked for use with any GSM carrier.
