It used to be you could have ESN's of other carriers devices added to Verizon's database, as long as they met certain requirements and were approved. Once they took over Alltel, all existing Alltel ESN's were added to the Verizon database, but in such a way that they cannot be used on a Verizon account, only on acquired Alltel accounts.

Alot of people used to do this with the Alltel touch pro, because the Verizon version was crippled, but they were no longer able to do this after the acquisition was complete.
