I am currently studying abroad in Japan. I was interested in getting a iPhone4S through AU. I live with a homestay and I can get a iPhone4S through them. My question is if I buy a iPhone4S in Japan can I use it in America and Europe? I plan to return to the US next year for about two or three months and then study abroad once more in Europe maybe France or Germany. I just want to make sure I can use the iPhone4S at those locations. This is the first time I have purchased a iPhone. I know there is not much information on the 4S at the moment in regards to this. I was wondering if people who have purchased an iphone 4 before in Japan were able to use in their respective country.
