Nokia's line of Windows 8 phones will be introduced at a media event scheduled for next week but we've already got our first look at what the phones will look like thanks to some early leaks. Twitter user @evleaks recently posted images of what he / she claims is the mid-range Nokia Lumia 820 and the higher-end Lumia 920 with PureView.

The Lumia 820 (pictured above) will reportedly ship with a 4.3-inch display and be available on AT&T and T-Mobile networks while the larger 4.5-inch 920 will likely have a resolution of 1,280 x 768 (or comparable) and is said to be an AT&T exclusive. The handsets are probably the Arrow and the Phi (respectively) that have been the topic of recent rumors but we won't know for sure until next week.

The higher-end model will likely ship with PureView, a camera technology boasting up to 41-megapixels that we first saw on the 808 PureView smartphone at Mobile World Congress earlier this year. This technology has been in the works for more than five years and could give Nokia's new flagship handset a significant advantage over other phones on the market.

Gotta Be Mobile notes, however, that the camera doesn't look nearly as large as the one on the 808. With that said, the 920 might technically still use the same PureView oversampling technology but with fewer megapixels in play.

Both smartphones are expected to ship in a multitude of colors as shown in the leaked photos. Everything else, including pricing, remains a mystery at this hour.
