Two screens with a bunch of possibilities! Aaron takes a first look at the Kyocera Echo, the first Android phone with two displays for maximum viewing. It has a 1 GHz processor, dual 3.5-inch displays, a 5-megapixel camera with HD video recording, and Android 2.2. Lock the displays together, and you have a mini tablet computer. It's a unique concept, but is it going to take off with Sprint customers, given its lack of 4G?
