So, has anyone checked whether the CONTACTS involved was still correct, or whether sync screwed them up?
As I said, we may be barking up the wrong tree if the problem is actually a sync problem.
I checked the contacts on mine, and they were correct. I also did nothing but exit messaging and re-open the thread a few times, and the problem "corrected" itself. However, the only real problem I had was that the incorrect name was displayed in the message thread. My reply went to the correct contact, despite the incorrect display.
