Motorola Photon (Sprint) Moving outside of its Droid franchise at Verizon, Motorola unveiled the Photon, its latest Android superphone, for Sprint last month. The Photon has a 4.3-inch screen, an 8-megapixel camera and it is powered by Nvidia's ( NVDA) dual-core Tegra 2 processor. The Photon runs on the Gingerbread version of Android and uses Sprint's 4G WiMax flavor of fast wireless. The Photon is similar to the Motorola Atrix at AT&T, and like the Atrix, it can be docked to a PC for larger-screen computing. The Photon is expected to launch this month at Sprint, but no price has been announced.
