I am moving to London from the States in mid-2008, and an wondering what my options might be for my iPhone. I'll have had it just over a year (of my 2-year contract) when I leave. Has anyone heard anything from AT&T or O2 about moving from one country to another and keeping your same iPhone? I realize that I may have to buy out my AT&T contract (not sure if there's a provision in there for getting out of that if you move outside of the service area). But my bigger question is, can I sign up for an O2 contract with my current phone? Or will I need to get an entirely new phone for use on their network?
