I want to be able to make my own ringtones on my mac and then send them over via bluetooth to my Razr. I have all the bluetooth working and I am able to transfer songs, pictures and videos to their respective sections but I can't get songs to go the 'ringtones' section on the phone. Are there certain requirements for the bit rate or file size? Like I said I have no problems transferring over 128kb mp3s. I just want to be able to use them as ringtones. Thanks, EDIT: I'm on the Telus network and I'm pretty sure that none of the features are blocked.
