i am studying in new york city and obviously cannot wait to get my hands on the new iphone. BUT: if I have to leave the US in one year, what happens to my phone? and to my plan? as far as I know it is possible to have the att plan cancelled without the early termination fee if you have significant reasons (such as leaving the country for good...), BUT will my iphone work in Germany then? is there a different 3g-system? and will it be locked after i terminated my att plan??
