We stopped by Kyocera’s CTIA booth to get a second tour of the dual-screen Echo from Sprint. The device, which will be available on April 17th for $199.99 with a 2-year agreement, really does have some innovative features. Applications and games that are optimized for the echo can leverage the second screen to display an enormous, thumb-friendly keyboard, provide more on-screen information, and enhance game-play. Kyocera assured us that the hinge on the device is ready for battle, and should stand up to most of the use and abuse inflicted by teens and tweens — the two main groups the phone will be marketed towards. The hinge itself was a bit finicky when we handled the device, however. Hit the break for more, including a video, and don’t forget to check out our Kyocera Echo photo gallery.
