When I connect my dad's iPhone 3G to his MacBook Pro, iTunes pops up with an error message saying it can't sync the iPhone because the computer isn't enabled for syncing. When you click enable syncing it pops up another message with two options: override and cancel. Whichever option you choose, it syncs the phone anyway! It's an annoying message that pops up every time you connect the phone, how can I get rid of it? Thanks, Ams.
