Abstract
Outgoing phone calls can be made on a handheld electronic device that has been locked to prevent unauthorized use through an override that permits the making of outgoing phone calls while applications additional to the phone application remain locked. In some embodiments, the override can not be selected unless first enabled by a remotely generated enable override authorization signal.
