iPhone 3gs 16GB! Cheap, Swaps considered! ?

Here for sale is my iPhone 3gs, the condition is okay. Hardly any marks on the front and usual marks on the back (some scratches) It is currently on the 02 network but is jailbroken so can be easily unlocked, the only thing is the mute button does not work im not sure why but im sure it will be an easy fix (currently stuck on silent) I will consider swaps, so let me know. and offers are welcome. Thanks for looking.
