I have a friend in Germany who asked me 1) can a non-US citizen buy an iphone 4 in the US with no commitment? 2) can a sim card be then replaced in it so it can be operated in Germany or is it locked to AT&T and cannot be unlocked. I remember at one point they were selling iphones with no commitment, then they started selling them at credit card only, and I don't remember how the story ended.... so what are they doing these days: Can I buy an iphone 4 with no commitment (provided it will cost me more of course) and do I need to show US Passport/ Drivers License and do I have to pay with credit card? I told him to look on ebay of course as another route. But what's their policy right now?
