I have a 3GS and my wife has a RAZR. I am not eligible get a new iPhone HD for a lower price until Feb. 2011 so I would be paying around $400 like I did last year unless the price drops. My wife, on the other hand, can upgrade and get a new iPhone HD for $200 unless the price drops. My question is this. Can she order the iPhone HD online with her cell # and when we get it can I place my simcard into it and use it with my cell # instead? So what I want to accomplish is to have her order the iPhone HD, pay $200 and when we get it I would use my simcard and she would basically continue to use her RAZR. Does anyone know will the new iPhone use the same type of simcard the 3GS uses?
