How much could I sell a old iPhone 4 for?

Its a 16gb Black iPhone 4. Its with Verizon. It is in good condition. How much could I sell it for?

It could go for $180. That's what all iPhones at that specification go for. Generally as a fussy buyer, I'd try get one for 150. But I've seen and have sold iPhones in a decent condition, 16gb locked for 180. One time I got it up to 200 on a bid. If you want it to sell quick, go between 150 and 170. If you want it to get sold but within any time frame, go 180. If you want it to be at a fairly high price because you don't care much for its sale, go 200 ;D I've seen brand new ones for 205 though xD
