Abstract: A controlling party can set limitations on a controlled party's access to applications operating on the controlled party's wireless mobile communication device. The controlling party can effectuate these limitations via various different mechanisms. In one instance, the controlling party uses another wireless communication device to effectuate the limitations. In another instance, the limitations are effectuated by the controlling party's operation of a data apparatus connected by a wired data communication bus to the controlled party's wireless mobile communication device. In a still further instance, the controlling party effectuates the limitations by accessing a website supported by a web server.
