LAS VEGAS -- The Nokia Lumia 620 has found a home at AT&T's new Aio prepaid brand. Like its unlocked counterpart, Aio's Lumia 620 is an entry-level Windows Phone 8 handset. The 3.8-inch display with a 800x480-pixel resolution (WVGA) has a polarization filter that cuts down on glare.
Though it has a plastic shell, the handset is sturdier and heavier (4.5 ounces) than you might imagine. A bright color and rounded edge complete the look. The Lumia 620 is 4.5 inches tall and 2.4 inches wide by 0.43-inch deep, which makes it smaller than most smartphones today. Up top is the lens for the 5-megapixel camera.
