I upgrade every year so long as ATT covers me which they are again this year. I never look to make money just cover my upgrade costs. I figured that selling the 4 would be more difficult than the 2/3/3G due to more on the market. I must have priced them too low. I have an 8 month old in perfect condition at $275, a 13 month old in perfect at $250, and then my 13 month old which could be in better shape. Never a case on it, dropped a few times, etc...at $200 or the whole lot for $650. 35 emails when I got home today from a 6am posting, all of them with local contact numbers. I dont' care about doing any more than covering costs but I was surprised by the response.
