BlackBerry Messenger allows instant communication between your BlackBerry unit and members of your BlackBerry Messenger contact list. The contact list information is also helpful for using the BlackBerry’s text messaging, emails and telephone features. There are two ways to restore contact list information to a BlackBerry smartphone: associating the BlackBerry device with a previously registered BlackBerry email address, or restoring a backup of the BlackBerry contact list. Without these advance preparations, lost contact list data cannot be retrieved. Both methods require connecting the BlackBerry to a computer on which the BlackBerry Desktop Manager is installed.
