The Helio Mysto isn’t that mysterious after all, since it is nothing but a rebranded Samsung SPH-A523. Basically, this is a CDMA version of the Samsung U600, also known as the Ultra Edition 10.9. All these naming conventions will surely have anyone confused, but this 10.9mm slider will come with pretty impressive features like a 3.2 megapixel camera, a QVGA display, touch sensitive buttons, EV-DO and stereo Bluetooth connectivity, and GPS functionality. No word on pricing and availability, but soon would be a good bet. Needless to say, it will run on the Helio interface unlike the Samsung U600.
