I have a iPhone 3gs 8gb for sale, there is a barely visible crack on the screen but like i said this is barely visible. Comes complete with Charger and USB Cable but no box. It is currently locked on Vodafone, Cost to unlock is £10 from the phone shop on Charles Street. Also if you wanted to repair the Crack on the screen, you can buy on off eBay for £5. As i have before.
£140 is a good price and would only cost £15 to get it unlocked and screen repaired. Current price on E bay for this phone is at £170.00.
The crack dose not effect the phone function and the screen do still work.
