Sanyo MM-5600

my initial focus in purchasing the 5600 was the mp3 player. the camera and camcorder functions have been upgraded since the 5500 and the 7400, and overall it is a really solid phone. i've been playing with data transfer for about 20 min. and i havent figured out if it can play mp3's for ringers yet ?? if anyone has the word on that please let me know, cause that was one of my biggest hopes for the damn phone.
