I have a jailbroken and unlocked iPhone 3G which does not save calendar events. I go through the usual steps to enter an event in the future and save each step of the way. At the end, the event is shown for a few seconds in the list, then disappears for another few seconds, reappears a few seconds later and then disappears completely. I have tried removing any other calendar apps, checking that the correct time zone is selected etc to no avail. I just cannot save any calendar events!
I have checked google for similar problems but cannot find any reported problems like this. Can anyone help me? Please???
