Betting big on Windows Phone and its new Lumia smartphones was a ballsy move for Nokia. Despite minor shortcomings on the Lumia 800 and 710, Nokia's managed to sell 1 million Lumias, putting the company back on track to growth.

The Lumia 710 isn't the only Nokia smartphone coming to the U.S. Intel points to AT&T getting a larger and faster variant of the Windows Phone 7-powered Lumia 800, rumored to be called the "Ace" or "Lumia 900."

All eyes are on Nokia right now. Last Thursday, it announced the official launch of the Lumia 710 on T-Mobile — the first Windows Phone 7 smartphone it will release in the U.S. Back in October, I had the lovely opportunity to play with prototypes of the Lumia 800 and the Lumia 710. As I said in my hands-on and review, the Lumia 800 is a handsome piece of polycarbonate, whereas the Lumia 710 was really just a poor man's version and a lower 5-megapixel camera instead of an 8-megapixel one. Nokia might not be a huge player in the U.S., but it's still a global one that still sells lots of cellphones in Europe and Asia; the company still knows a thing or two about making phones. Choosing Windows Phone 7 to be its smartphone OS of choice moving forward was surprising indeed. Now that we've had enough time to let that fact sink it, can Nokia re-enter the U.S. and become a dominant force once again? Can it stare down the mountains of iPhones and Androids and claim a stake on the pedestal? I'm not saying it has no chance at that, but it certainly doesn't look like Nokia's going into this with a huge bang.

Nokia is showing off a supremely crazy phone concept called HumanForm. Shaped like a teardrop, this is a touch-activated and completely flexible phone that looks like it's straight out of a sci-fi movie.
