Nokia unveiled its third Windows Phone 8 today, the cheapest model yet.

Joining the Lumia 920 and 820, the Lumia 620 will sell for $249 and go on sale in Asia in Jan. 2013, followed by Europe and the Middle East. No word on when it will be available in the U.S.

It will come in seven different colors and an exchangeable shell, which is part of the “youth appeal” that Nokia is going for. The 620 features a 3.8-inch display, a 1GHz dual-core Qualcomm Snapdragon S4 processor, 512MB of RAM and a 5-MP camera.

Here’s the Lumia 620 data sheet as well as the press release.
