Can you use an Alltel phone on Verizon network?

Ive been looking through the Blackberrys and think Ive settled on the BB 8830 if the Storm isnt up to par. Ive found one that was from Alltel and would like to pick it up but Im not sure if you can use it with Verizon. They are both on the CDMA network but Im not sure if thats all that matters. BTW, only reason I want the Alltel one is the color; Alltel is all black where VZ is Silver. Gay I know.

the ESN needs to be added to VZW’s database. They just officially aquired Alltel. I would hold off on doing this if you absolutely need to for a bit, as you should be able to do this shortly.
