Has anyone else had problems with iPhone 4 calendar reminders not working since update to iOS 4.2.1? I live and die by my iPhone calendar and my calendar reminders popped up just fine until I updated to 4.2.1 last week. Since the update, I have only seen two calendar reminders pop up. I didn't notice that this was not working consistently until I missed an important meeting last Friday afternoon. I have already tried restoring the iPhone and this occurs both with events set previously to the update as well as new events created after the update. i figured I would post here before i go Genius hunting at the Apple Store. ...and, yes, event notification is turned on.
