At the risk of beating a dead horse ... .
NokiaUSA currently lists the E90 and says of it:
"Get high-speed 3G mobile broadband connections for Internet browsing and file transfer"
It's true that there is a footnote saying that "Many features and mobile services require network support." But given that no network in the US supports the E90's 2100 MHz 3G connection, the initial claim is at least irresponsibly misleading.
Whether it's evidence of dishonesty or incompetence I don't know. Given that it's a very high end and expensive item, I would think the loss due to people buying it and then being annoyed, as I was, when they discover that the high speed connection cannot be made to work in the US would be larger than the gain due to people buying it because of the claim and keeping it anyway.
