Another FCC filing, another battery compartment label: this week we're looking at an outline of Samsung's SPH-D600, sailing through federal approval with CDMA / EV-DO and WiMAX support. The filing says little else about the device, save the usual suspects: Bluetooth, WiFi, and GPS -- though Pocketnow is reporting an unverified gigahertz processor, 3.1 megapixel camera, and 320 x 480 display. This device is heading to Sprint, but if you'd rather not wait for details, big brother Nexus S 4G is almost there already.
