Abstract
The apparatus and method for transferring radio specific data from the memory of an integral logic unit of a radiotelephone to a second, replacement, memory is disclosed. Security of the data is realized by encoding the radio specific data with an operative number generated from a seed number. If the radio specific data is properly transferred to the second memory, the radio specific data is deleted from the memory of the integral logic unit.
