Abstract
A wireless communication device stores a system GUI configuration file and a downloaded service provider GUI configuration file, each of which contains a text name checksum value that is calculated using the text names of the GUI parameter data stored either the system GUI configuration file or the service provider GUI configuration file. The text name checksum values are based on the text names of the GUI parameter data. After the download operation is complete, a text name checksum comparator program compares the downloaded text name checksum value to the initial text name checksum value in the system GUI configuration file. If the two text name checksum values do not match, the downloaded service provider GUI configuration file is rejected.
