I have an iPhone 4 (16GB, Black, Verizon) -- and I'm finally out of my contract. I'm re-upping with Verizon for an iPhone 5 next week -- when I get my upgrade. I had my iPhone 4 replaced by the Genius Bar about three weeks ago, so this iPhone is almost in mint condition. I've checked it closely under a bright light, and I see 2 minute scratches on the back, almost impossible to see in normal conditions. That's it. No other scratches, blemishes, screen scratches/damage, water damage, etc. Clean bill of health. Considering that this is 2010 hardware (even though the CDMA model was rolled out in Feb. 2011), what's a good asking price?
