Microsoft and Nokia jointly announced the Lumia 820 and 920 at a press event in New York last month, but stopped short of committing to a price point or release date. Though that’s still pretty much in the air for would-be US buyers, today AT&T announced it will carry both of Nokia’s upcoming Windows Phone 8 devices starting November, with the higher end Lumia 920 launching exclusively on the company’s LTE network.

The two phones are seen as critical to Nokia's short- to mid-term success so it’s a little surprising that they didn’t go for wider availability of their flagship device. Then again, such deals could guarantee Nokia dedicated support and carrier-backed marketing campaigns for its devices. Last year, Nokia also launched its Windows Phone 7 devices in the US with AT&T as its premier partner, but ultimately sales failed to take off.

There's still the possibility that Verizon may have a modified version of the Lumia 920 or that the AT&T’s exclusive is time-limited, but so far neither Nokia nor Verizon have made an official announcement. In contrast, the HTC 8X and 8S have already been announced for AT&T, Verizon, and T-Mobile.

The Lumia 920 iterates on Nokia’s previous flagship with a 1.5GHz Qualcomm Snapdragon S4 dual core processor, a slightly larger 4.5-inch (768 x 1280) curved glass display, a 2,000mAh battery, and a one-piece polycarbonate body. It also features an 8-megapixel PureView camera, built-in wireless charging, and comes in a variety of vibrant colors including red, white, black, yellow, and cyan.
