I got the new 9700 today and while I was all fired up to use a phone with 5.0OS, I am having serious problems with the new SMS. Here are the steps I took.

1. Restored data from previous berry. SMS messages ended up "threaded" which was really cool.
2. Noticed that one of my SMS threads was "repeated" in Messenger because it from a person who is also a Messenger contact.
3. Chose to "close conversation" in Messenger of the SMS threads. Noticed that by doing that the thread in the SMS folder was also gone.
4. Using the "advanced" feature of the "backup and restore" in Desktop Manager, I replaced the SMS on the phone with the SMS from my previous device, which I had backed up before the swap.

However, the problem is, no matter how many times I do this, or whether I do a battery pull before the restore, after, or both, the SMS thread that I had "closed" earlier will NOT come back, even though it is clearly the same data that i restored earlier. It WILL show back up in Messenger, and Messenger only, as a threaded SMS, but as soon as I do a battery pull, it goes away.

Ideas? Anyone? I keep SMS messages practically forever so this is going to be a HUGE problem if I can't figure out why it is doing this....
