Lost all contacts after iOS 4.3 update [iPhone 4]

Hello Apple this issue needs to be resolved NOW!

the calendar upgrade we were required to make at me.com, which is my interface to my Windows Outlook calender, erased all of my Outlook calendar items in Outlook on my PC They recreated them on a separate me.com calendar whcih I now have to open separately in Outlook. I cannot put items in my regular Outlook claendar and have them sync with my iPhone. Anyone else have that issue?

I had that problem about 3 weeks ago, it has caused a real problem with losing most of the peeps I talk with the most. as they call I add them back.

Any word from Apple on how to fix this?

I am all numbers now. So annoying.

I just updated to 4.3 and my contacts and photos are gone. I restored back to my previous sync but they are GONE! I am not happy Years worth of contacts gone!

Same problem here. iPhone 3GS. They were there after the 4.3 upgrade which I did a few days ago. But today when I sync'd to get a new podcast I noticed all of my contacts were gone. When I resync'd again I got an ancient version of my contacts that look to be at least a year old despite me regularly syncing and backing up my data. A restore from backup results in the same ancient contacts list.

I'm f-ing mad and there doesn't seem to be any solutions to this. Thanks Apple!

Well I managed to find a solution for this issue for me.

First, I went into the Time Machine backups for the Mac my iPhone was sync'd to. I restored the contents of ~/Library/Application Support/MobileSync/Backup to the date of the last backup I made prior to upgrading to iOS 4.3. When it told me that there were filename conflicts I told it to keep both the original and the restored versions.

Then I went into iTunes, right clicked on my iPhone and chose Restore from Backup and selected the backup from that date.

After about 10 min of restoring, everything is back to where it was (although I've lost the changes I've made since that date).

I'd also tried restoring to the backup made the day I did the 4.3 upgrade but that was missing my contacts. I'm guessing Time Machine didn't catch the sync made before the upgrade and only got the one that happened after.

I'm now concerned that 4.3 isn't backing up all of my data as it should be since I'm sure I had the correct contact list until yesterday but the backup I made on 3/16 after upgrading to 4.3 did not contain my contacts apparently.

There is a simple solution to recover your address book and contacts. Connect your iphone to your computer that you normally use for iphone backup. Go to itunes and right click on the name of your iphone. That will give you a pop box saying "restore from back up". It will show the backup dates available. Restore from the days before the system was updated.
PS the back up files are hidden files making it difficult to find, so you won't delete it by mistake.
I hope this work (and if it does pass it around). It worked for me after I updated to OS4.3

This *****.

I updated 2 iPhone 4s last Saturday on an XP. I even had to reinstall iTunes because it wouldn't open. I tried to do a backup prior to the update but it kept on saying that the phone was disconnected. I went ahead with the update expecting to loose everything but was surprised to see that everything was still there - or so I thought. Thinking that everything was fine, I went ahead and updated my wife's phone. It took her's longer because the backup seemed successful. Her's actually worked! The main difference between our phones is that I came from iOS 4.2 while her's was from 4.1.

To make things worst, for some reason I now can't send nor receive emails on the phone. Both my Yahoo and Gmail accounts don't work. I've tried deleting and recreating both accounts but I always get a message saying that the Apple server is not responding or my settings are incorrect.

Lasty, we noticed that the Personal Hotspot would intermittently dissapear.

Me too, updated to 4.3 and all contacts gone. Nightmare /___sbsstatic___/migration-images/migration-img-not-avail.png/___sbsstatic___/m igration-images/migration-img-not-avail.png

People are saying did I back them up.....isn't that what Itunes is meant to do 😟

Can anybody help us here ????

Linomalino:

This was not sufficient in my case.

I first restored the most recent backup (via iTunes) as you suggested and my contacts were still missing.

Then I restored the backup (via Time Machine) of the iTunes backup made the day I upgraded to 4.3. Because I still had my contacts at that point I assumed that whatever caused them to disappear after synching to get a new podcast would be there. My contacts were still missing. grepping the files on the filesystem in that backup for things I knew were in the contacts list showed no matches.

To get my contacts back I had to restore the backup (via Time Machine) for the iTunes backup made prior to the upgrade and then restore that version via iTunes to get my contacts back. grepping the files in this backup on the filesystem showed matches for things I knew were in my contact list.

My only conclusion here is that since 4.3 or due to a post-4.3 iTunes update, syncs are not providing a complete snapshot of my phone. I find that to be very concerning. At least as concerning as the fact that my contacts just disappeared one day.

So no updates on this thread? is there another thread regarding this issue (which has just happened to me!).

I now have no address book, mobileme, iphone or ipad contacts!

Whats the thoughts of the world: is Apple software poor or is Apple's approach extremely arrogant?

I'm having a similar problem after updating to 4.3 and it's driving me crazy.

I noticed today when some of the meetings I created on my iPhone were not on the Exchange server and some of the meetings I created in Outlook are not on my iPhone. I turned off calendar sync with my Exchange on the iPhone to clear the entries and turned it back on, but some of the calendar items will not sync no matter how many times I reset it.

I then decided to check my contacts and sure enough the latest contact I added to my iPhone never made it to the Exchange server. I'm not sure if the Exchange contacts are syncing to the iPhone yet, but I suspect they are not.

APPLE WE NEED A FIX ASAP! I left BlackBerry for iPhone because of how well the Exchange integration worked, but now it's REALLY BROKEN! 😟

I am on 4.3 and not sure if I should update to 4.3.1?

no one from apple reads these forums. its just users helping users.

What is curious to me is that you have one and only one copy of what seem to be very valuable contacts. they couldn't be that valuable or you would have multiple backups locally and off site somewhere.

That being said, what version of outlook/exchange are you running? I recently had a client running outlook 2007, which was workable but very unstable with iphone 4. AND outlook 2011 on the Mac has lots of problems, hopefully that will be fixed in a service pack.
