iPhone 4 16gb Unlocked and Jailbroken ?

Had it under a year. It was in warranty so got a replacement from Apple. Its unlocked to all networks and running on 5.01 firmware which is jailbroken. If you dont know what that means then google it! Phone works great, i have had no problems with it. There are no scratches on the screen or on the back. There is one or 2 light scratches on the area where the volume button is but hardly noticeable. It comes fully boxed with charger, headphones etc. I will throw in my case as well. I am selling it for £240 but open to near offers and no silly offers please.
