Samsung announced today that the Moment phone will be the first mobile-DTV phone. They will start trials with the phone in 1Q 2010, in Washington and Baltimore. Samsung has chosen the Moment because of its "big, bright AMOLED screen".
The Moment has a 3.2" touch OLED, full QWERTY slider, 3.2mp camera, microSDHC slot, Wi-Fi and GPS. It runs Google's Android OS (on a 800Mhz processor). It is now selling for $79.99 (with a service plan) for the Spring network, and it's actually the top-selling smartphone over at amazon.com.
