Heralding the launch of Windows Phone 8, the Nokia Lumia 820 serves as one of Windows Phone 8's launch devices. While it may technically fall under the category of a "mid-range" device, the 1.5 GHz dual-core Snapdragon S4 processor packs a serious punch. The speedy processor is backed up by 1 GB of RAM, 8 GB of ROM, HSPA+ and LTE connectivity, a 1650 mAh battery, and a WVGA AMOLED display.
