I woke up this morning to a working phone. Yay! First thing I did was synch, of course, which didn't work. I got this dialog box, even though the iPhone was still connected. I've had trouble using iTunes auto-synch with my iPod, so I synched everything manually. This worked fine, except for the calendar, for which I still get this error message.
Otherwise, it's beautiful, but I can't love it yet. I want it to be 100% working, dammit!
Note: this is a followup post to iPhone: I'm officially pissed off
