New iPhone competitor runs on Windows 8 operation system.
Another volley has been fired in the smartphone wars.
Nokia and Microsoft have teamed up against Android and Apple devices.
Nokia's Lumia smartphones will be among the first to use Microsoft's new Windows 8 operating platform.
It's an alliance Nokia hopes will reenergize a company that has been dethroned as the world's top phone maker, while Microsoft looks to establish a mobile operating system that can rival Apple's IOS and Google's Android.
Nokia says its top of the line Lumia 920 phone will offer wireless charging, a display better than HD and a high end camera for sharper images and more stable, smoother video.
Nokia did not reveal a price for its new phone, but said there would be a cheaper, mid-range version, the Lumia 820, and that both phones would be available before year's end.
