Iphone 4 16GB box only ?

I have box only in great condition, as I sold my phone year ago without it cos I couldnt find it, now after moving in new house I found it and I remember when I was selling my Iphone in the shop in Edinburgh I got 70 pound less for it just because I didnt have a box. Learnt my lesson,if you are thinking about to sell your Iphone and you dont have a box be aware- you will be loosing at least 50 quid. drop me an email if you are interested.
