activation code from a first wireless device, comparing the first
activation code associated with the first wireless device with a first
activation code in a database, activating the first wireless device when
the first activation code associated with the first wireless device
matches the first activation code in the database, and when a second
wireless device is active, deactivating the second wireless device in
response to receipt of the first activation code associated with the
first wireless device.
