iPhone 4 32GB Black unlocked with receipt ?

iPhone 4 32GB Black unlocked. The phone has no marks or scratches. I have always used case and screen protectors. It comes with box, book, earphones, cable, wall charger and receipt everything original Apple and a case. Software version iOS 5.1.1 (which is jailbreakable). If you want I can leave it like this or I can update to the new version 6.0 (currently without jailbreak). Collection from Willesden Green station Zone 2 Jubilee Line. Just call me or drop me a line for any question. Selling due to upgrade. Thank you. Giorgio
