Iphone 4S 32gb brand new on o2 *

For sale I have a brand new black iphone 4s 32gb, its on o2 network, still in the original protector, comes boxed with all accessories which are also brand new. You will be buying from my house in Derby so you can put your full trust in me otherwise I wont be selling from my house. Warranty expires 1st June 2012 so approx 10months left I can also unlock this iphone using a gevey sim but for this the buyer will have to pay £15 extra, but then the phone will be unlocked on all networks or you can just buy it as it is on o2 network.
