Following it's earlier commitment for Windows Phone 8, Nokia today announced its third, and so far most affordable Windows Phone 8 Lumia smartphone - the Lumia 620. Alongside the flagship Nokia Lumia 920 and mid-range Nokia Lumia 820, the Nokia Lumia 620 offers a more fun, youthful appeal, and compact design. The Nokia Lumia 620 uses a new dual-shot color technique to deliver a variety of striking color and texture effects. Dual-shot adds a second layer of colored, transparent or translucent polycarbonate on top of a base layer to produce secondary color blends and depth effects. With seven different exchangeable shells to choose from, people can adapt the look of their Nokia Lumia 620 to their own personal taste and style.
