I'm moving to Europe next summer, right at the point my two year initial contract with AT&T expires on my 3GS. I'd like to be able to continue using the phone and all its capabilities once I'm over there, but am not exactly sure what all I need to do in order for that to work. I imagine it includes getting the phone carrier unlocked in the US before leaving (will AT&T do this once the contract is finished?), then getting a new SIM and data plan for a carrier in the country I'm going to. Could some kind soul let me know what I'd need to do step-by-step to accomplish this, and if there's anything I need to be especially careful about along the way? Thank you -
