Someone solve my problem for me.

I seriously just don't have time for this… When I plug my iPhone in, it goes:

iTunes could not sync contacts to the iPhone "Julia's iPhone" because the sync server failed to sync the iPhone.

… and of course, doesn't sync anything. All of the advice I can find about it on Google are LIES! FILTHY LIES! So to save you some time; I'm not running exchange or Yahoo anything. I've completely wiped my phone to factory settings — leaving it in a even less useful state than before &mdash erasing all of my contacts with the OSX Address Book utility, and Reset Sync History in iSync.

Here's a clue no one else seems to have noticed so far:

	The parser will retry as in 10.2, but the problem should be corrected in the plist.
