Hi gang - I'm a new Motorola V3 Razr owner (woohoo! I got it super cheap, too), and it does mp3 ringtones. In theory, I can use mp3 clips and have a totally customized experience. I had no problem making a clip, getting it shrunk down (using Amadeus II for Mac OS X) and transferring it to the phone via Bluetooth file transfer, and it even shows that it's an audio file when it downloads, but once it's transferred, the phone says 'file format not recognized' and when it tries to play the file, I just get silence. I've saved it as an 8kbps mp3 file, no tags, and I've tried it with the vbr_rh, vbr_abr and vbr_mtrh algorithms, with and without 'strict ISO compliance' set, and get the same result. Anyone know how to save an mp3 file so a motorola phone can read it?
