Barring unwanted phone calls on a BlackBerry 8800 phone can be done in two different ways: You can use the "Mute" option to block specific people numbers from calling you and showing up in your Call Log, or you can download call-blocking software from the BlackBerry App World to your phone. Most call-blocking software, which will reject all unwanted calls, costs a small fee.
