I've been having problems with my SMS for the past couple weeks (if there wasn't an active message thread open, I could only read the alert and nothing more).

Complete backup yesterday, Flashed and restored just now.

Checked the messages on my phone - only has restored my side of the conversation.

Is it something I've done, something I can fix? Complete conversations are readable in Nokia Suite... why not on the phone?

If I "synch" it, will I lose everything in Nokia Suite for the one-sided stupidity on the restored N900? There are some important and meaningful messages I don't want to lose (in addition to those from today I've lost) and want on my phone.
