Calendar sync deleted iphone calendar and replaced with "On my mac" cals

Guys, you should only have to do this MobileMe dance once. Once you get all of the calendar onto the Mac/PC through MobileMe, it will stay sync'ed in iTunes. I was also able to sync my iPad in iTunes and the calendar sync'ed fine. I did not have events on the iPad, which is what started me down this whole road, as I really had just wanted to move my iPhone calendar to the iPad. I suffered through about 10 restores before I figured out how to get it done.

Good luck to all and glad that this workaround has helped.

I had a similar problem yesterday after a routine sync to add some music, on the 3G iphone I've had for a year, all my most recent appointments are gone.
It's never happened before! Super frustrating.
(I'm on a Mac)

So far it seems to have worked. (haven't done final step to sync from iTunes back to phone) I now have my calendar OFF the phone and into MobileMe and into iCal which makes me rest easier.

FYI: Make sure you set your timezone correctly for your account in MobileMe to prevent a slight heart attack when you see all your appt's at the wrong time in the MobileMe calendar. Even if you don't set it correctly, once you do it will put all the times back correctly.

Thanks again to MX727!

I tried doing what you both suggested (with MobileMe), but I still didn't get my old calendar back from my itouch that was deleted. Did you get your old calendar back or did this just help with your future calendars?

When you did this were you able to get your "deleted" calendar back onto your iphone? I tried what you suggested with mobileMe, but I wasn't able to get my deleted calendar back. Any suggestions?

After our calendars were deleted, we got them back by "restoring from backup" and then following the MobileMe path. So, you need to select a backup that has the calendar, restore it and then follow the advice here.

If you don't know how to restore, post back and we'll walk you through it.

I went thru the restore procedure, however, restoring from backup didn't provide the data that once existed in my itouch. Is there a place where the data resides in backup that I'm unaware of???

I have changed to a mac from a PC (several Months ago) and had been putting off the sync of itouch with mac until now. Multitude of calendar entries since last hooked up to PC. All Gone? or is there some way to retrieve??? I certainly hope there is.

Ok, when the restore dialog comes up, are there older backups in the drop down box?

If you don't have a backup with the calendar info in it, then I'm afraid you've lost those items.

Thanks, I'm officially screwed. The thing is I selected the option to merge the files. It seems that it should have worked. Oh well. rebuilding the data is not going to be easy.

Regards, and thanks for the response.

hi,

I'm using iPhone with Iphone OS 4.0.2 (8A400) and was trying to sync with my MacBook with MacOS X 10.6.4 and with iTunes 9.2.1 (5).
After synchronization, all events that i put on my iPhone were gone - deleted. The only
events left where those from my iCal 4.0.3 (1388) on my MacBook. How on
earth can that happen? Why are all my events that I put on Iphone are deleted?
Is there any way I can get them back, from the backup that was made before
synchronization? I really need those events, and I trusted iPhone, that it won't delete them.
Did I make a mistake, is there a option that asks you wether to overwrite your iPhone-calender
with the iCal calender?

Please help me. Thank you, klavus

I just updated my iphone 3gs to 4.0.2 last night and today I noticed that all of my calendar entries from when I last synced(about 2 weeks ago) are GONE. Are you f *ing kidding me apple? My LIFE was on there, telling me where I needed to be and when, what I needed to do. Now I have to try and remember everything and restore it all. And yes, I still want old calendar events incase I want to refer back to.

I just wanted to post this up and let apple/everyone know that this is not an isolated case.

The calender is also in the backup that iTunes do before every sync with the phone. So if u restore from the latest backup u will have the calender (and everything else) as it was when the backup was taken. Check in settings-devices or something where u can see when the latest backup was made. If it was made long time ago theres no way to get it back i guess.

Next week 4.1 is released, lets just hope it will fix this problem 😟

In my case, my cal info on Me is apparently corrupt so I want to replace the info on my Mac Pro with the cals from the iPhone 4 and sync that with Me. As with some of you, the iPhone is the primary. With iTunes 10 the sync no longer overwrites the iPhone but I still cannot get the cal info from the phone to the Mac Pro.

This is SO UNAPPLE!

If any Apple mgmt is reading, you need to let us specify the phone as Primary and let it overwrite all or any of the others.

Thanks,

I have worked for a whole week to try to get my iphone cal sync with the outlook cal, and suffered 6-7 times restores, it was devastating that suddenly all of my iphone cal was gone a week ago, lucky the immediate restore (before a new backup without the iphone cal overwrites the backup with the iphone cal) saves the iphone cal on iphone.

this post is extremely useful and thanks for everyone here. I thought this was only my problem before but now it seems it is a common VERY SERIOUS ISSUE, and APPLE MUST FIND A SOLUTION TO THIS ASAP. I was waiting to pick up an iphone 4 order next month and this seriously affects my confidence on the reliability on iphone.

Anyways I just updated the itunes to 10.0 and iphone to 4.0.2 also the office outlook update (07 September 2010) as well as windows vista business. I am going to try to sync it to experiment it works or not.

Thanks for you guys.

BIG NEWS!!!!!!!!!!

IT WORKS FINE AND FINALLY... THE IPHONE CAL IS ON THE OUTLOOK CAL AGAIN... FINALLY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1

UPDATE TO ITUNES 10.0, IPHONE 4.0.2, OUTLOOK (07 SEPTEMBER 2010), VISTA BUSINESS (07 SEPTEMBER 2010).......T_T

WORKED FOR A WHOLE WEEK AND NON SLEEP IN WEEKENDS.
