I looked up a few random phones from curiosity - specifically, the Samsung Galaxy S Fascinate, Focus, and Motorola Droid - and all gave me a value of 0.00000. Is this a bug, or does nobody want 3-year-old crap
EDIT: Yeah, most older phones seem to have a value of 0. The newest thing I could find is the Galaxy Nexus, and that netted ~0.6 BTC. I would imagine newer, popular phones (atleast) would be listed, like the Galaxy S III and HTC One X. Furthermore, there's no change in value from "good" and "flawless".
Otherwise, I like where this is going. A few kinks worked out, and it would be sweet.
