AT&T has officially announced that it will be ranging the Nokia Lumia 920 and 820 from November. The Lumia 920 will be exclusive to AT&T and will be available in black, red, white, yellow and cyan. The Lumia 820, which is not exclusive to AT&T, will only be available in black, but AT&T stores will be stocking the removable coloured shell accessories.

While no exact availability date or pricing has been announced, both devices will support LTE on AT&T's network. This means support for bands IV (1700/2100) and XVII (700) will be included, necessitating US-specific variants.

The two Lumia devices will join the already announced LTE version of the HTC 8X as the launch Windows Phone 8 devices on AT&T.

The Nokia Lumia 920 is the flagship device with a 4.5 inch PureMotion HD+ display (1,280 x 768 resolution), 1.5GHz dual-core Snapdragon S4 processors, 1GB RAM, 32GB internal memory, wireless charging, a 2000mAH battery, and a PureView 8 megapixel camera with optical image stabilisation and Carl Zeiss optics.

The Nokia Lumia 820 is a mid-tier device with a 4.3 inch ClearBlack OLED display (480 x 800 resolution), 1.5GHz dual-core Snapdragon S4 processors, 1GB RAM, 8GB internal memory and microSD card support, a swappable polycarbonate body, and an 8 megapixel camera with Carl-Zeiss optics.

Jeff Bradley, senior vice president – Devices and Developer Services, AT&T Mobility, said:

"Exclusive to our customers and featuring unique innovations in imaging technology, wireless charging and a bright, sensitive display – all on the nation's largest 4G network – the Lumia 920 will be one of the hottest phones for the holidays."

Olivier Puech, president of Nokia Americas, said:

"We welcome AT&T's decision to offer the Nokia Lumia 920 and Nokia Lumia 820, which, when added to what we've witnessed in other markets, underscores the momentum behind our Lumia devices and the broader Windows ecosystem. Our continued collaboration with AT&T is an important component for Nokia's success in the U.S. market."
