Nokia Lumia 520, coming soon to a carrier near you
BARCELONA, Spain--Nokia's Lumia 520 is a fairly entry level Windows Phone that will find its way to a number of carriers globally, including a variant for T-Mobile in the U.S., called the Lumia 521.
Nokia has given its 520 a round back to fit into the curve of the hand. The contrast with the phone's squared face edges makes it less comfortable around the rim.
