Best Buy has dropped the price of the Nokia Lumia 520 to half. The Lumia 520 price now costs $50 instead of $100 through the AT&T GoPhone program. This lets buyers prepay for devices without signing up for a two year contract. There are four plans under the contract that costs between $25 and $60 per month. The Lumia 520 has a 4-inch LCD IPS screen, a Qualcomm Snapdragon processor, 5 megapixel camera, 8GB storage, and a 64GB microSD expansion option.
