Nothing new. Before North America wasn't really the most important market and big mobile phone makers like Nokial and SE could make huge profits and grow faster than rest of the tech industery with no presence in NA, but now part of Nokias problem is that NA is now catching up Europe and Asia in smartphone saturation in a big way(thanks to iphone) and Nokia is totally left out of this.

By far largest thing is that i believe E71 is only carrier supported Nokia Symbian phone and a phone that came to att 6-12 months after Europe and Asia release. This in the country where real unlocked phone market dosen't exist and they are stll ahead of Android that got several carrier subsidized phones. That said that's more about Android not being long enough in the martket. Will be just matter of time.
