Worked for me. I had a contact that got stuck always showing my sent messages as pending, and the status updates properly now. I used sqlite3 on the phone to edit the db in-place instead of jacking around with copying files back and forth and screwing with permissions (I still made a backup beforehand, of course).

Is it possible to programmatically recover the remote_uid? I noticed that the messages that were missing remote_uid still showed up in the correct conversations.

Any update on the possibility of getting this into the CSSU?
