I have a 16GB iPhone 3GS that was just unlocked today from AT&T. Previously it was jailbroken and unlocked. As I have sold more recent models in the past, I do not know what a reasonable asking price would be for an unofficial unlocked device that is two models behind. I checked eBay and as this is recent for AT&T there aren't any I could find. It's in perfect condition. I also am including a Brookstone iPhone 3GS charging plate, and will jailbreak the device should the buyer desire. Thanks!
