I am moving from New York to Amsterdam in two weeks and hope to unlock my AT&T iPhone 3GS for use in The Netherlands. Questions: 1. What is the best way to jailbreak and/or unlock? 2. Which Dutch carrier(s) would my unlocked iPhone work with? 3. What sort of contract would be necessary? 4. How much should I expect to pay per month for service? If there are any Dutchies on here, thanks in advance for your help!
