Samsung Behold T919

If you've had T-Mobile for more than 90 days (sometimes they make exceptions if you haven't had them 90 days-tell them you signed up under the impression that you'll be able to get a code immediatley), call them and tell them you're travelling overseas. They'll give you an unlock code. If you don't have T-Mobile, call some locally owned cell repair shops... they'll be able to do it or will be able to point you in the direction of a store that can.
