Turns out the rumors were true - Sprint and Kyocera have partnered up to build the Echo, the world's first dual-screen phone.
The two 3.5" 800x480 screens offer 4.7 inches of real estate when combined, and can be used as:
- One huge display ("Tablet Mode")
- Combined displays, where one screen can show a keyboard while the other displays the email app ("Optimized Mode")
- Two individual displays with each running a separate app ("Simul-Task Mode")
- One single display, with the second hidden underneath ("Single-Screen Mode")
Unfortunately, the rest of the Echo's specs aren't nearly as innovative - its battery is puny (1370 mAh, though Sprint will include a spare), it doesn't have a front-facing camera, and there's no 4G connectivity to speak of.
