I still have one 16Gb Black 3G iphone. it has a dent on one of the corners and minor scratches on the back (not that visible). The screen is perfect (has had a screen protector since day one). It comes with the earphones, USB cord, and wall charger (ie the accessories that came with it), but not the box. I can unlock it for you.
as for the price, whoever gives me the highest price until sunday takes it. (lowballers' profile walls will be spammed with May Chidiac's and Nefnefeh's pics

).
and in case you don't know yet (and for the sake of transparency), the new iphone is going to be released in july (check out this link for more info about the new specs and features:
Apple - iPhone - Mobile phone, iPod, and Internet device. ). One important thing, these iphones will have the 3.0 version installed on them (and only God knows how long it would take the hackers to overpass this version's restrictions).
I can post pictures when I go back home on Saturday.
