Iphone 4 well looked after but must go!! .

Ive got a black iphone 4 (16gb) in good condition. Its boxed and on orange. I want to sell it for £250- the price is fixed so will not go lower. Alternatively I would consider a swap for something good so start offering if you want my iphone 4 :) .. The person with the best offer gets my iphone tomoro or any day they wish to have it :) thanks for looking and please no blackberry devices except the playbook plus cash on top!!
