My contacts are not appearing in BBM
If you saved a backup file of your contact list to your smartphone, on a media card, or to your computer using the BlackBerry® Desktop Software, you can restore your contact list using that backup file. Depending on your organization, if you previously associated an email address with a smartphone on which the latest version of BBM™ was installed, you might be able to restore your contact list over the wireless network. Research In Motion recommends that you regularly create and save a backup file on your computer, especially before you update any software. Maintaining a current backup file on your computer might allow you to recover smartphone data if your smartphone is lost, stolen, or corrupted by an unforeseen issue.
