You'd have to use a gevey sim, from what I understand. However, you still have to be careful with updates, lest you lose the capability; it's dependent on the modem baseband. CDMA providers are really awful when it comes to moving to another network; they've locked down the network to where a factory unlocked phone from apple doesn't work on a cdma provider.
If your verizon is world unlocked, you should be able to sell it for a decent price out of country.
