    b) upon detecting the transmission, comparing, by the monitoring computer, the software application serial numbers to stored software application serial numbers for the communication unit based on the unique unit identifier; and

    c) when the comparison of step (b) is unfavorable, reprogramming, by the monitoring computer via a second communication resource of the wireless communication system, at least a portion of system access information contained in the communication unit;
