Can't edit events after updating calendar

[S-Steve]

I logged in to MobileMe and updated my calendar to the new version. Since then I can't edit events on my iPhone 3GS running iOS 4.2.1. I don't use MobileMe to sync my iPhone calendar–I use iTunes 10.1 (under OS X 10.6.5) to sync the iPhone calendar with the Mac. Does that make the calendar read-only on the iPhone under the new format?
