Details of the unannounced Motorola ROKR E8 music phone have become public on the FCC web site. The bar-style phone sports a unique flat keypad with illuminated labels that disappear into a glossy black surface when not in use. Four large piezoelectric actuators under the keypad presumably provide some form of haptic feedback. The phone also sports a landscape display, micro-USB port, sliding key lock switch, camera, stereo Bluetooth, EDGE data, and a microSD memory card slot located under the battery cover.
