I have lots of mp3s that I sync between my MBP and iPhone all the time. However, anything I purchase through iTunes does not sync over to my iPhone. I get a message after trying stating that I don't have authorization to do that. "Some of the items in the iTunes library, including "name of a song", were not copied to the iPhone "iPhone" because you are not authorized to play them on this computer." Does this have something to do with the fact that I just had a new logic board installed? If so, what do I do to fix the issue? Thanks in advance... Edit: Okay. I got one part fixed. It appears I had to resync with .mac and now that's fine. But it's saying I've got 2 out of 5 computer sync'd. In other words, .mac seems to think I have another computer sync'd with my account. Is THAT because of the old logic board? Or is the second computer my iPhone?
