A prototype Dell Thunder smartphone has leaked out and Engadget laid hands on it for some playtime. Engadget actually got to play with two of the prototype units and had enough time to shoot a video review of both of the units that carried an April build date.

The devices are said to include an AT&T quad band unit and one that is aimed at T-Mobile. Both handsets ran Android with one getting 2.1 and the other using 1.6. The handsets both have a 1GHz Snapdragon processor and Qualcomm Adreno graphics.

The devices also have WiFi, a FM tuner, HDMI out, hardware dock connector, and dual mics. The handset has a front and back camera and the screen on one has an 800 x 480 resolution, and the other has a 1280 x 768.
