T-Mobile simply calls this Windows Mobile 6.1 smartphone the "new Shadow". Its feature set is nearly identical to the original Shadow by HTC but the casing and design are all new. Also new is UMA WiFi calling for unlimited domestic calls over WiFi if you add T-Mobile at Home service. The Shadow 2 features a slide-down SureType 20 key keyboard with predictive text, a QVGA display, 2 megapixel camera, Bluetooth with A2DP stereo and WiFi. It's a quad band GSM world phone with EDGE for data and it's available exclusively on T-Mobile.
