Now i've moved to the android world with my dell streak, my iphone 3G is surplus.
It's about 18 months old and in pretty good condition. Has a zagg invisible shield on the rear which has been there for a while (not from new though) but i never liked the front shield so removed that and therefore the front has some minor scratches (as you can see in the pics below).
It's running iOS 4.1 and is officially unlocked via O2 so ready to go on any network.
It will come with box, charger and cable but i've lost the dock (found a 2G dock though!).
