There was a post a year ago about this but no definitive answer. I created some ringtones in garageband and synced with the iPhone. No problem. I then wanted to add a few songs manually and checked this option off. I then created a new ringtone and did another sync. It indicated I would loose all music, movies, etc. I did this and it did delete all the music. Is there a way to sync ringtones and not loose the music on the iPhone? If I uncheck manually manager music and movies, will that keep the music? I do not want auto sync as I only want selected music on the iPhone and not everything in the Library.
