Contact Groups not showing up on Iphone when syncing with Mobileme

I'm having the same problem with the Verizon iphone 4. I sync my contacts through mobile me as well. When I go to "groups" under contacts it is blank and I have no way of getting back to the full contact list.

I've tried syncing many times, as well as checking mobile me settings etc.. Anyone else having this issue??

well I cant get my contacts to sync at all and my contacts are in groups....

Same problem here. I even tried turning off & on the contacts option under mobile me to no avail. I have turned off Over the air syncing, and sync directly from my iMac. This at least lets the groups show up until it is fixed.

I actually got the problem resolved lastnight I ended up going back to MobileMe tech support chat and talking to another rep and told him how was on the line for several hours this morning and how ended up going and getting a new phone and problem exist well this guy was like I see your username has some capital letters how are you entering in your phone I was just like appears with the capital and lowercase letters... He said needs to be all lowercase so I deleted the account on my phone re-added in all lowercase and magic works... so now my contacts/bookmarks are Over the Air syncing again.

I am having a similar issue. As is my wife. I also believe that it is a bug in the current iOS on the CDMA iPhone 4.

It is just as you described, and I have to close Contacts completely in order to restore my access to the contacts list. And, like you, our groups show up just fine on our iPads (within minutes of making changes, as we sync over MobileMe).

It doesn't appear to be a letter-case issue, as at least my login is in all lowercase letters.

I sure hope that this is fixed in an iOS update soon! It's rather problematic for those of use who use their iPhones for business purposes.

Ok here is the problem. I put new phone numbers in my phone. But as soon as it syncs with MobileME instead of pushing the numbers to the other devices to deletes them. This is a new problem. I have had MobileME for years and its never done this. Its just the new numbers that are gone.

I have the same problem with my new AT&T Iphone 4. My log in is all lower case. any one find a fix?

Update: Found the fix!

Remove the Mobile Me account from the iPhone, and add the account again (turning on the desired sync options, namely contacts).

After doing that, I opened the contact app and my groups were there.

Removing and re giving the MobileMe account details worked for me. Was wondering if anyone else had allowed iTunes to provide account details on restore or setup of the phone.
