Not quite sure what you mean... When you say you set up your computer first, does that mean that you added your dates into ICAL first, then synced to your IPHONE? If I attempt to start all over again, I'd have to delete my appointments on my IPHONE and put them in to my ICAL first? Yes, I am using Mobile Me. I can just give up and use only the calendar on my IPHONE, I suppose.
I am feeling dumb.
