US Patent 7725889 Mobile handset capable of updating its update agent

A mobile handset in a mobile services network, with access to a plurality of services including a firmware/software update service, is also capable of updating its update agent using an appropriate update package. The update package is retrieved from an update package repository via a management server. In one embodiment, the existing update agent is copied to a backup section before the update agent itself is updated. On the subsequent reboot, the new update agent is employed unless it is determined that it is corrupted or ineffective, in which case the old update agent is reactivated.
