I've been having problems all day...
If I create a calendar appt or contact on the iphone, it gets pushed up to MM.
If I create the same on MM, it does not go to the iphone.
If I delete something from the iphone, it gets deleted from MM.
If I delete something from MM, it doesn't get deleted from the iphone.
Mail hasn't been pushing either.
I was on a chat with Apple for like 1.5 hours, until they told me they need to escalate the issue to their next level support.
They had me reset the phone to factory and resync like 4 times...
My Exchange Active sync is working flawlessly.
I'm so annoyed, everything was working great ever since the day of release for me... now nothing.
