I noticed when I back up and restore software versions/apps/backups the following happens...
1) My BB Messenger Conversations are not restored, possibly due to them not being backed up in the first place. Contacts only are there.
Are they able to be backed up and restored?
2) When restoring, I always end up with 3 sms messages being placed at the current date of the restore above all other messages. I think the messages used to be on my SIM card and/or are still on there I think...
Is this why they show up and restore as they are doing?
1) No, the conversations aren't backedup that I recall. If your conversation partner sends another message, it usually continues from that point forward.
