Hi all, After I updated my iPhone 4S 64 GB to iSO 7.0.4 and JB the only problem I had was that Music didn't want to sync via iTunes. The iTunes claimed that all was OK but on my iPhone the Music app had "No Content". I managed to fix that (please check this thread): "Music shows "No Content" after JB and data restore..." http://forums.macrumors.com/showthread.php?t=1692707 but afterwards 16 GB "Other" appeared on my iPhone! In iOS 6.1.2 my "Other" was 1 GB which is considered normal / regular. I strongly believe that was the 1 GB of normal "Other" + my 15 GB Music collection that wasn't synced properly! So... how to remove that orphaned failed music sync that causes the 15 GB of "Other"? Thanks in advance for all help!
