So, I don't understand people. I just sold my 8GB iPhone 3G
(not 3GS!!!) for $200 on ebay.
And there are a shitload of people selling 3G's and 3GS's on there, so its not like there wasn't a lot to choose from a buyer's viewpoint. I just listed it a few hours ago, and this guy flat out bought it (didn't bid or anything). Verified through ebay and paypal, so he is real.
It wasn't even jailbroken (not hard to do, I was just lazy). Can't be unlocked (upgraded firmware). So either he wants it for parts or he is using it on AT&T pay as you go.
I listed it after the iPhone 4 announcement, and the announced price drop of a
new iPhone 3G 8GB to $99 with 2 year contract.
So, being eligible for an early upgrade, I shave a few months off of my AT&T shotgun marriage and get the new iPhone basically at no cost.
