Kyocera Echo is a dual-screen Android smartphone with two 3.5" touch displays, which actually allow for a healthy sized 4.7" (800x960) real estate when combined. In closed mode, the Kyocera Echo is your typical Android 2.2 Froyo smartphone. It comes equipped with a powerful 1GHz Snapdragon chipset, 5MP camera, Wi-Fi and GPS. Unfortunately, it only sports 3G bands, no WiMAX compatibility.
"We just had some hands-on time with the Kyocera Echo for Sprint, one of the most unique Android phones we've ever seen. With two full-size (3.5-inch) screens, this phone transforms into a small Android tablet when fully open, or you can tilt one screen up like a tiny laptop (or like an HTC Tilt, or a Nokia Communicator.) Behind the fancy new screens lie a 1 GHz processor and 5-megapixel camera with HD video capture, while data is 3G (EVDO Rev. A). In other words, this isn't the ultimate top-end super-phone. With that said, the specs are respectable enough for all but the most demanding power users." (Rich Brome; phonescoop.com)
"Though cell phone carriers like to boast that their devices are "one of a kind" and "industry firsts," the claims are usually nothing more than marketing speak. With the Kyocera Echo, however, Sprint wasn't just feeding us a line." (Kent German; senior editor for cell phone reviews at CNET)
