I set up iTunes a while ago with the checkbox to only sync "selected playlists, artists, albums...". For some reason though my iPhone 4 has my entire library on it even though I only put checkmarks on a few artists. It seems like iTunes does not see all of the music that is on my iPhone. iTunes used to allow me to only have the music I selected on my iPhone but my entire music library is on my iPhone now. And I don't have the 'entire music library' checkbox on (just a few selected artists). Is there any way to delete music from the iPhone manually. I am JB on 4.2.1 and unlocked and I am trying to avoid restoring but will if I have to. Can I manually go into the music folder and delete all the songs - that may just corrupt the file system and make me have to restore. After that - syncing may work correctly? Any other solutions? Thanks a lot..
