I have had a search but was unable to find anything relevant. I own an ipod touch and just bought an iphone 3G for me and one for my wife. I am trying to have different music files in each of the three devices but I am failing miserably. It just shows me one library. I have 'assigned' different files to the three 'playlists' I created (one for each device) and chosen which playlists each device should synchronise with. Despite that, when I go to 'music' in the library it shows me everything. How can I categorise these music files to show me only the ones relevant to the device I have connected? Please help, this drives me mad!
