WHat is the simplest way to get an Mp3 onto my BB 7250. I tried attaching it to an e-mail but I could not figure out how to download it. Secondly if Mp3 format is not supported, what are the supported formats? I play in a christian rock band and I like to have one of our songs as my ringer. I have only had the phone for 3 days now so I am a complete Newby.
