Say hello to the new, potentially life-saving low-end of Nokia's Lumia lineup: the Lumia 620.

Aimed at entry-level customers, the 620 features some fairly bare-bones specifications. Its 3.8-inch screen comes with an uninspiring 800 by 480 resolution, and its cameras only take 5-megapixel shots.

But the appeal here isn't in those numbers but rather the device's price: The Lumia 620 retails for $249 before carrier subsidies, meaning that, in many cases, buyers could get the thing for free.
