With built-in iTunes software, surround-sound quality speakers and the ability to hold up to 100 or even 500 songs, the ROKR provides a unique cell phone experience. Besides its audio capability, the unit has a display that can show full-screen movies and videos, as well as an integrated VGA camera for taking pictures. The unit has an illuminated keyboard, white-light backlighting for the LCD screen and a white LED Flash lamp for the camera.
