A method of enforcing a time limited software license of a software application code in a mobile communication device, wherein the software application code is bundled with a license certificate, thereby creating an application bundle, the application bundle located on an application server, the method of enforcing comprising:

• loading the application bundle into the mobile communication device from the application server;
• authenticating the license certificate;
• installing the application bundle into a non-volatile memory of the mobile communication device;
• attempting to invoke the software application code for execution by the mobile communication device;
• upon performing executing the software application code, obtaining a secure time reading from a secure time server;
• comparing the secure time reading with a license period of the software application code, the license period indicated by the license certificate;
• and
• executing the software application code only if the secure time reading is within the license period of the software application code;
• wherein the loading, authenticating, and obtaining are performed by the mobile communication device by establishing a network connection over an air interface of a communication system with which the mobile communication device is affiliated.
