Since updating to iOS5 on my iphone 4, my one music playlist (sorted by date added) has been completely reversed. The playlist in itunes is from earliest to latest BUT my iPhone is now sorting the playlist from Latest to Earliest. It is super annoying. I have tried to re-sync the playlist but to no avail. I may have to restore it. Anyone having problems like this? ---------- FIXED! For those having problems: I duplicated the playlist in itunes and selected the duplicate to be synced and that fixed the issue.
