Abstract
A mobile voice communication device including a wireless transceiver circuit for transmitting and receiving voice communications and for receiving data; a digital processor; and a memory storing application program code which when executed on the digital processor causes the mobile voice communication device to provide predetermined functionality to the user of the mobile voice communication device. The predetermined functionality includes basic features and it includes enhanced features that are in addition to the basic features. The application program code has a deactivated state in which the mobile voice communication device provides the basic features to the user without providing the enhanced features and an activated state in which the mobile voice communication device provides the enhanced features. Toggling between the deactivated and activated states is accomplished by receiving through the wireless transceiver circuit a transmitted key that was sent by a remote source to that mobile voice communication device.
