My CFO had a Blackberry with a large list of ringtones that he had downloaded. He now has a droid and wants to be able to use his old ringtones from his Blackberry. The Blackberry ringtones all end ma4.rem. I have searched the web for a reliable file converter but have yet to find one. Can anyone suggest an application ( preferably free but does not have to be ) that could help me solve this issue ?
