Unlocked black berry question?

Can i buy a unlocked Blackberry Curve 8530 from amazon (CDMA) and use it with verizon?

Depends if it's actually the Verizon branded version.  CDMA devices don't get "unlocked" as the carriers here require the device to already be in the system so a Sprint Blackberry won't work on Verizon and vice versa.
