So I am really excited for iOS4 and don't know if I will be able to stop myself from updating tmrw lol. But since I AM selling it as soon as I get my iPhone 4, I want to try and sell it for as much as I can. It is in fair condition with a few scratches on the back so I am aiming for 200-250. Now would the price make a dif. if I jailbreak or update it tomorrow to iOS4? If so about how much?
