I see a lot of mention about trade in values but I can't really find any threads on people selling their iphone 5. (I looked in market place and couldn't even find any threads.) Ours are black, at&t, 64gb. I'M NOT LOOKING TO SELL MY PHONE ON THIS FORUM (which is why i posted here in the iphone thread vice marketplace)! I just need the current going rate so I can list it on my local sale site. (We only do in person sales for cash.) thanx in advance for any help!
