Just downloaded the latest iOS from Apple, and everything seemed to have gone smoothly except for the fact that the calendar on my phone had a duplicate of all events.
I checked my phone sync settings on iTunes and noticed that I had the “Sync iCal Calendars” box selected.
Since iOS5 is now using iCloud to sync calendar events between all of your devices, apparently it’s no longer necessary to have this box selected.
Your calendars are being synced with iCloud over the air. You can also choose to sync calendars with this computer. This may result in duplicated data showing on your device.
So all you’ve got to do is this:
- Plug in your iPhone
- Open iTunes
- Click on your phone under “Devices”
- Click the “Info” Tab
- Uncheck the “Sync iCal Calendars” box.
- If I remember correctly, it asked if I wanted to remove all of the events from my iPhone calendar. Yes.
- Sync again, and now your iPhone should show the proper events in your calendar. i.e. one of each, as opposed to the duplication.
Enjoy your iOs 5. I know I am.
Not sure how we ever survived without the notification center and other notification improvements.
