I currently have an iphone 4 running 4.2.1. The phone is jailbroken but this issue I have had before the jailbreak and still have it after the jailbreak.
When a calender reminder sounds, it will keep going off every 5 minutes even if I dismiss the event. It will continue to go off even if I delete the event. It doesn't seem to matter if I have the event scheduled to start and stop for 1 hr or 1 minute. The only way I can get it to stop is to reboot the phone. I have my calender setting set for Repeat:never Alert:none
