I like to use my Treo 680 to play MP3s using Pocket Tunes. Is there anyway to get the phone to ring or get notification from SMS to override the music? I would like to be able to hear the ringtone if I am listening to music. I know that there is a visual notification, but I keep my Treo in its holster so I don't see the screen. So far, I can't find any easy way to do that. Any suggestions?
