16. A system for updating wireless communication device, wherein the wireless communication device includes a memory, and wherein the memory includes a direct-addressable portion and a non-direct-addressable portion, the system comprising:

an update package, the update package transmitted to the wireless communication device over-the-air; and

an update agent on the wireless communication device, the update agent applying the update package on the wireless communication device to perform an update on the direct-addressable portion of memory in the wireless communication device, including the installation of an agent in the direct-addressable portion of the memory, the update agent then executing the agent on the wireless communication device to update the non-direct-addressable portion of the memory;

wherein the agent updates the non-direct-addressable portion of the memory to disable over-the-air update package functionality of the wireless communication device.

17. The system of claim 16 wherein the agent is removed from the wireless communication device after agent is executed.

18. The system of claim 16 wherein the update package comprises an update based on a difference between a current state of the direct-addressable portion of memory and a desired state of the direct-addressable portion.

19. The system of claim 16 wherein the agent on the wireless communication device performs a record-by-record update of the non-direct-addressable portion of the memory.

20. The system of claim 16 wherein the agent on the wireless communication device performs a record-by-record update of the non-direct-addressable portion of the memory using API calls on the wireless communication device.

21. The system of claim 16 wherein the wireless communication device comprises a wireless telephone.

22. The system of claim 16

wherein the update package installs the agent as part of a power-up power-down procedure in the direct- addressable portion of the memory.

23. The system of claim 16 wherein the memory comprises firmware.

24. A method of updating wireless communication device, wherein the wireless communication device includes a memory, and wherein the memory includes a direct-addressable portion and a non-direct-addressable portion, the method comprising the steps of:

transmitting an update package to the wireless communication device over-the-air, the update package comprising update an update based on a difference between a current state of the direct-addressable portion of memory and a desired state of the direct-addressable portion that includes an agent for updating a non-direct-addressable portion of memory;

applying the update package on the wireless communication device, the update package performing an update on the direct-addressable portion of memory in the wireless communication device, the update package installing the agent in the direct addressable portion of the memory;
