Need a new cellphone /want mp3 player and navigation computer

[guids]

Im very happy with my current setup.

Sprint A900 cell phone, plays mp3s, can connect to my FM transmitter and can listen to songs over my car radio.

Dell Axim 51v, with GPS, cna use the cell phone as a bluetooth modem (high speed EVDO), and can get on the internet like a normal PC. Memory cards etc, can hold MP3s, also conneects to my car transmitter.
