BenQ-Siemens EF51 puts music front and center

The BenQ-Siemens EF51 doesn't seem to break a lot of ground when it comes to phone features, but if you want something that looks and works like a music player (and just so happens to also be a phone), it could be a good choice. The EF51 includes a 128x128 display, support for MP3, WMA and AAC, voice navigation for the music player and support for stereo Bluetooth headsets (yes!).
