iPhone 4 Black Good Condition ?

Hi Guys, This is an iphone 4 in good condition on iOS6. Previously jailbroken so able to downgrade if necessary. This iphone comes with a receipt as proof of purchase and a charger cable and ac adapter. We accept cash and are based in Hither Green. I have a history of conducting online sales of mobiles and accessories. During the day I am based in Chelsea, West London so can meet there if necessary. Email me with any questions.
