Okay, so yesterday I realized it has nothing to do with updating Tiger for Mobile Me. I could just go on using the .mac service like I always had. The only thing I had to do was open the settings on the iPhone and activate synchronization for the calendar and contacts on the .mac account. It now works fine. I think Apple has been a little evasive regarding this piece of information, don’t you?

Well, it was easy enough when I realized what to do. … tsk… and I call myself a geek…
