A best bet is to activate a new 2-year contract for a LG Optimus Elite Smartphone for Sprint in Black (pictured) together with a $50 Walmart Gift Card for 1 cent with free shipping. Assuming you use the credit, that's essentially a net profit of $50 and the best price we've seen for this phone. (It's a current low by $50.) Features include a 3.5" touchscreen LCD, 5-megapixel camera, video recording, GPS, wireless and 3G connectivity, Bluetooth, up to 7.2 hours of talk time, and Android 2.3 OS (Gingerbread).
A $36 activation fee applies.
