A system for licensing an application or feature for use on a wireless mobile device is disclosed. The wireless mobile device is provided to a user with a licensable application or feature, but the application or feature has not been fully authorized for use. When the wireless device receives a request to use the application or feature, the wireless device operates the requested application or feature, and generates an irrevocable license request. The license request is transmitted to a license server at a time convenient for the wireless device. The license server generates a license certificate to the application or feature, and transmits the license certificate to the wireless mobile device. The wireless device receives the license certificate, which is stored in local memory. Accordingly, the application or feature is now fully licensed for future operation on the wireless mobile device. The license server operates accounting processes to generate license reports and license accounting information.
