Kyocera

The Echo has two 3.5″ touchscreens, which can form a single 4.7″ display at 960 x 800 resolution, perfect for viewing videos or using two apps at once. Available via Sprint this Spring for $200.

Not to be outdone by Motorola and Dell, Kyocera returns to the US with the Zio M6000, an Android smartphone with 3.5″ WVGA display, trackball, Wi-fi, and 3.2MP camera with video.
