iPhone 16gb factory unlocked white ?

I am selling my beloved white iPhone 4s. It is factory unlocked and was bought direct from Apple sim free last year on launch day. Has been used with a case since purchase so is in perfect condition. No straches on screen or back. Has been reset to factory settings yesterday, so works as new. Only reason for sale is because I just got the iPhone 5. I have receipt of purchase, supplied with box and original charger (with usb attachment) and the original apple plastic bag. Unfortunately I do not have the original headphones, but I do supply a black case which protects the back and sides of the phone and is black. 300. Cash in hand only, I work during office hours, but will be checking my emails. I have the phone on me today just off Oxford Street, so can sell today after 5.
