Sprint's own website appears to have tipped what's likely in store for us at tonight's event. Confirming earlier reports, a search for the Kyocera Echo returns results for "The world's first dual-touchscreen smartphone" -- something the Samsung Continuum might raise an eyebrow at. The site describes it as:
The Kyocera Echo smashes the last barrier between you and the ultimate mobile experience. Its unique dual-touchscreen, pivot hinge design gives you all the space you need to run the apps that connect you to the people and information you need every day. Spread your work across all 4.7 inches of combined display or use each smaller display independently to run multiple apps. Closed, the Kyocera Echo is a pocket-friendly smartphone. Open it and expand your world.
So we've got a hinged display with a total of 4.7 inches of real estate, and you can use one screen at a time, or both. We'll find out tonight whether it's truly magical, or just a bunch of smoke and mirrors, so join us for the liveblog! Thanks, Sketch42!
