Abstract: A portable electronic device or wireless communication device (WCD) has at least one provision for optional equipment or user services. Options are provided for a user in a menu selection for selection by the consumer of the options. The user selects the options for the particular WCD and the options are installed on delivery or prior to delivery, thereby providing the user with an initial selection of the options.
