You can create contact
alerts that allow you to customize ring tones and alerts for calls and messages from
specific contacts or groups of contacts. When you receive a call or message from the
contact, your BlackBerry smartphone uses the assigned ring tone or alert, even if you select
the Silent profile or Vibrate Only profile. If you do not want to be notified with the
assigned ring tone or alert, you can select the All Alerts Off profile.
To delete a contact alert, highlight the contact alert that you want to
delete.
