The BlackBerry Curve 8900 from T-Mobile is the lightest and thinnest full QWERTY keyboard BlackBerry smartphone yet. The 8900 expands on the great features of the predecessor 8320 with a high-resolution 480x360 pixel color screen, a 3.2-megapixel camera, and built-in GPS for turn-by-turn navigation.
