Receive notification when a contact becomes available
Each time that you set BlackBerry Messenger to notify you when a contact becomes available, you receive a notification.
1. On the contact list screen, highlight a contact whose status is set to Busy.
2. Press the key BB> Set Contact Alert > OK.
To turn off the notification, press the key BB> Clear Contact Alert.
