Microsoft Store offers the Nokia Lumia 521 Windows Phone 8 for T-Mobile in Flat White for $69 with free shipping. That's the lowest price we could find by $21, although it was $36 less after rebate last month. It features a Qualcomm Snapdragon S4 1GHz dual-core processor, 4" 800x480 IPS LCD, 512MB RAM, 8GB internal memory, 5-megapixel camera, microSD slot, WiFi, Bluetooth, and Microsoft Windows Phone 8 OS.
