Apple Iphone Black 16gb ?

Apple Iphone 4 16 GB in Black. Phone has been used for 12 months but is in great condition, has been kept in a case with both back and screen protectors which has resulted in no scratches on either front screen or back panel, just a couple of marks from the bumper on the side of the phone. Phone is curenlty on Vodaphone. You will struggle to find a second hand iPhone in as good condition! Comes with box and leads with paperwork but no headphones. Cash on collection, Thanks!
