I want to sync my music and photos at home (iMac) and everything else from work (MBP). This seems to work OK except for music and apps: 1. Music: after I sync with my playlist at home...even though I have 'Sync Music' unchecked at work, iTunes seems to automatically change the preference to 'Sync Music' on when I plug my iPhone in. At this point, I have two undesirable options: uncheck 'Sync Music' again (but this results in the music on my iPhone being deleted) or let it sync (but I don't have any music on my work MBP, so the music on my iPhone is again deleted). The weird thing is, this behavior doesn't happen for syncing Photos (can have sync checked on my iMac but not on my MBP without any problem). 2. Apps: I'd like to be able to sync apps on both computers. I've been syncing apps primarily with my MBP (work), but a few weeks ago synced with my iMac (home). So my iMac thinks I've got a very different set of apps than what I currently have (and what my MBP knows I have), so when I try to sync with my iMac it removes the apps that I've added since my last sync with the iMac. Sorry this is so confusing but it seems like it should be easier to keep the iPhone synced between two computers. Any input/help would be appreciated.
