Abstract: Many mobile consumer communications devices, such as cellular telephones, PDAs, laptop computers and the like, require an identification module to engage a wireless communications network. An arrangement with an identification module adaptor connected to a housing holding an identification module and a programmable processing unit adds functionality to the mobile consumer communications device. The programmable processing unit which is electrically interposed between the adaptor and said Identification Module is adapted to pass all data communications between the mobile consumer communications device (through the adaptor) and the Identification Module unimpeded for conventional wireless communications in one case, and to intercept the data communications with program applications running on the programmable processing.
