Upgraded to 5.1 on Wednesday, but calendar still blank on iPad 1 when I first open it. Flip and page and go back and everything is there. I'm hoping that will be fixed when I get my iPad 3/HD/The next...whatever they're calling it.
I've had the same problem since last summer. I recently went on vacation and switched off Location Services and noticed right away that my calendar opened with all events showing!? This hasn't happened in many months! I haven't had a chance to spend the time to see if the problem is due to one app or Location Services as a whole...Just thought I'd add my experience to this frustrating little glitch!
Original iPad running 5.1
I just recently got around to installing iOS 5.1 and noticed that this issue was still occurring. I filed a bug report, and encourage everyone to do the same.Did you guys file a bug report?
