Iphones

I've always considered myself to be a good consumer apart from those silly youthful years when I was an anticonsumerist, politically leftist vegetarian and so naturally I want the new awesome iphone. And by want I mean to say that a small part of me feels that my life would not be complete without one. But they're fucking expensive.

So, my American friends. If I were to buy an iphone in the US, how much would it cost me? Would I be able to ship it to Norway directly and would it run with a Norwegian simcard? How much taxes would I be expected to pay? Can anyone figure this out for me?
