The Lumia 800, Nokia's flagship Windows Phone model, will go on sale next month in Europe for 420 euros, or about $580. The once-dominant mobile phone maker debuted the device and a lower-end sibling, the Lumia 710, at its Nokia World conference in London today.

The profile of the Nokia Lumia 800 has the company's characteristic tapering.

The back of the Lumia 800 features a camera with an 8-megapixel sensor and a fast f/2.2 lens that Nokia boasts will yield superior image quality. It can shoot 720p video at 30 frames per second.

Atop the Nokia Lumia 800 is an audio jack. The company hopes the Windows Phone's music abilities will let it stand above the crowd.

The Nokia Lumia 800 has a 1.4GHz Qualcomm Snapdragon processor inside and a 3.7-inch ClearBack AMOLED display on the front.

Nokia's Lumia 710, a lower-end, lower-cost Windows Phone sibling to the Lumia 800, has less flash memory at 8GB but also costs 150 euros less. The Lumia 710 will sell for 270 euros, or $374. The Lumia 710 is expected to ship in Russia, Taiwan, India, Hong Kong, and Singapore later this year, with more markets coming in the first half of 2012.

Nokia wants a rich selection of accessories for its Windows Phone models--in part as a high-margin extra that will make carriers more interested in promoting and selling the phones. This case is for the Lumia 710.

The Lumia 800 will cost 420 euros before taxes--about $580--when the Windows Phone device goes on sale in November. The Lumia 710 will cost 270 euros--about $374.

To try to stand out above other Windows Phone models, the Nokia Lumia models come with software called Drive that offers maps, voice control, turn-by-turn navigation directions, and precached maps for when people want to avoid data charges or network blank spots.

Nokia Drive software can give navigation instructions by voice.

Nokia's music app for Windows Phone comes with a "mix radio" feature that lets people listen to streaming music without signing up for subscriptions.

Specific mix playlists can be pinned to the Windows Phone start screen.

Nokia also signed a deal with ESPN for sports videos, statistics, and other information.
