MetroPCS offers the Nokia Lumia 521 No-Contract Windows Phone 8 for MetroPCS for $49. This $20 mail-in rebate cuts it to $29. With free shipping, that's tied with last week's mention as the second best deal we've seen on this phone. (It's a current low by $51.) 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. Deal ends April 9.
