I have a problem with iTunes, it won't let me change to manual without synching my iPhone. I have it synced with another computer many miles away, and thought I would add some music from another computer. I then clicked the "handle manually" box on my iPhones menu in iTunes, and clicked apply. The thing is, that when I do this, an evil little box appears, asking me if I really want to synchronize this iPhone to this computer. Of course I don't want that, very much stuff would disappear, so I click no. When I do, the "handle manually" box unchecks, and I'm back where I started. So, anyone have a solution for this? I have tried intensive googling, but I haven't been able to find people with the same problem. Would be really nice if someone knew how to fix this, help is really appreciated.
