I was wondering if I am the only one with this issue... I have iTunes 7.6 and the latest 1.1.3 firmware on my iPhone and was expecting the manual disk managment to be like with my iPod Touch... namely plug it in and be able to add and delete music/movies manually except that it doesn't seem to work like that! In order to enable manual disk managment I have to click it on EVERY PC I plug it into - which then wipes the iPhone clean - Obviously it should not be doing that! Even when I selected manual managment on my PC that I was auto-syncing the iPhone with previously it didn't want to work properly - videos I deleted manually and were GONE in iTunes remained on my iPhone and would no longer show up as being there even though they still were and I could watch them. In the end I removed the videos from the playlist and resynced automatically and they vanished... now is it just me having issues here or has anyone else had similar problems with manual disk management?
