Sold mine for $300 for 16gb black in excellent condition with an applecare warranty. I got my new 3GS 32gb for the same price so it was a straight upgrade.
I sold my 2G iphone on ebay last week for £200 or $320 which i was very happy with. It was running 3.0 and was unlocked and jail broken. It was in used condition with marks on it but the screen was perfect. Getting my 3GS this week now i have got the PAC code from Vodafone.

Bought an iPhone 3g 16Gb Black on Craigslist for $290.
Met the guy in the evening outdoors.
Was hard to see the flaws evidently.
The next day it was a horror:
- cracked case
- chip off near headset
- dead pixels
- bright patch on screen
and took it to the apple store.
They replaced it no questions asked.
Sold that thing on Craigslist for $400
