My iPhone has stopped syncing with my mbp. It is driving me crazy. I have uninstalled iTunes, and restored my iPhone. When I try to re-sync my phone after doing all this the same problem: It shuts down after syncing about 3 songs. The songs don't make it to the phone! I think the calendar synced, and the contacts, but that is it. I was trying to put 25 songs on my 8GB iPhone, and there is plenty of room left, but it refuses to sync. There are no error messages or anything like that, it just stops working.
