Did you know that you can quickly back up all your BBM messages? Here’s how to do it in BBM6 or earlier. (BBM7 now backs up using BlackBerry ID.)
1. In BBM, hit the Menu key and scroll down to Options.
2. Scroll down to Backup Management and select Backup.
3. Choose whether you want to back up files remotely (online) or locally (to an installed microSD card).
