AT&T has come up with a new addition to its catalogue of music phones. Moto’s clamshell ROKR EM330 will soon hit the carrier’s stores with its stylish retro design. It has an external screen with touch-sensitive keys, which will allow you to dive right into that song you’ve been humming all day long. The ROKR should deliver an enjoyable music experience thanks to its 3D sound effect, SongID feature and audio equalizer with 11 different presets. It also has a 1.8-inch TFT main display and a 1.3-megapixel camera with video capture. The EM330 will be available through AT&T in Q2 2009 for free with a two-year contract agreement.
