Duplicate events in iCal and MobileMe after upgrading iPhone from 3G to 4

[sjshaw]

I just upgraded to iPhone 4. I have MobileMe and haven't had any syncing problems between my MacBook iCal, MobileMe web calendar, and Calendar on my iPhone 3G.

Now, whenever I modify a previously-created event on my iPhone, it creates a new event on MobileMe and my MacBook iCal with the newest event info, leaving the old one intact. No duplicate on my iPhone.

Any ideas to fix this would be appreciated. I thought about deleting the MobileMe account on the iPhone, as maybe something got wonky after upgrading to iPhone 4, but thought I'd check with you guys first.

Just seeing if anybody has some insight. Did a search and found nothing.

i had something similar to this on my ipod touch. I had syncing turned on (under the info tab) in iTunes as well as mobile syncing turned on... Might want to make sure the sync iCal...Mail... address contacts boxes are no selected.
I hope this helps

Thanks for the idea. I checked it, but that's not it. Of course, now the problem seems to have self-resolved.

If you click Calenders then Click the Calender button in top left you might have mobile me and your computer ical calenders checked to show both. You only need to have mobile me clicked to show your events.

Similar problem? No answers, just these clues:

Bought a mac so I could manage calendars/contacts for my office on 2 iphone 4s and ipad. Been syncing first 2007 thru outlook pcs then only thru mobile me when it came out. Bought a mac last week so i could manage thru iCal locally, even back up and abandon my outlook. Heck, maybe I would have fun. Me, a Mac, wow.

Now worse off. every mobile me sync adds a few thousand calendar entries, duplicates. I've disengaged my phones from mobile me to protect them from this compounding error. Spending my sunday deleting 60 entries per events for apparently random items dating back to july 2007.

This started happening to me as soon as we upgraded to the iPhone 4. We've been doing it with the iphone 3 with no problems... I hate that iPhone 4.

I'm going to be contacted by a senior level specialist soon-- maybe they'll have answers.

Meanwhile, here's a quick fix: Make sure your computer has all the most recent data. Then go to System Preferences, --> Mobile Me --> Sync and change from "automatic" to manual". Then what you do is you fix your computer--- in Address Book, under Card, you can search for multiple entries. Unfortunately for iCal, there's no such thing--- it has to be done manually Then, the next time you sync, choose to push/replace all the information FROM your computer TO me.com. That's the important part of the step. Once you do that, and once your phone syncs with me.com, then you can choose to sync automatically once again. It doesn't solve the root of the problem, but it's easier than manually deleting every single instance and having it reoccur almost immediately.

There is a way to gather and delete duplicate calandar entries in iCal. Entering a period "." in the search slot window on the upper right side yields a list of all entries. Pressing the column headings allows you to sort by date title color and type. I used a variety of these, mostly date to gather multiplews and delete them as a selection.

This is not a fix, just a clean up method. I have literally 5,000 duplicates, often 240 duplicates in a day.

Life is too short to delete one at a time.

I have just had a similar problem with my iPod Touch. My iCal is correct but my mother's birthday is listed like 50 times in my iPod Touch calendar. Has there been any resolution to this?
