I had set an calender event on my iPhone for the next day. I synced the iPhone with my Mac. But that calender event doesn't show up.
So I deleted the calender event on my iPhone and instead set it up on my Mac. Then I tried to sync both calenders again. No success. So I opened up iTunes, go to the iPhone device and checked the option to delete the calenders on that device. After that it synced the calenders to my iPhone again, but without this specific calender event!!!
What is going on?
