This isn't about carriers at all.

This is about how Nokia isn't going to distribute this phone to the USA via the official Nokia distribution networks.

Amazon is US based, isn't it? They'll have to buy their phones from Nokia somewhere, and Nokia US isn't stocking up. I don't have a full list of Amazon departments, but in EU, Amazon is also available from .co.uk, .de, .it, and .fr. UK, Germany, Italy, France; all of these countries are also missing from the availability list. Japan and Canada also.
