Iphone 4s 16gb in white 3 network .

i am selling my iphone 4s its white and is the 16gb model, it is in great condition and has been well looked after ,it has a few tiny surface marks but thats to be expect with a used phone and nothing bad that youd be dissapointed about.the phone is currently locked to three network but i was told it is cheap to get unlocked from any phone shop or stall . i am selling due to upgrading to the iphone 5.the phone comes with the orginal charger, box ,instructions and sim ejector pin thing,. email call or txt, would prefer email or txt as im at work alot and cant answer calls but can txt n email back, if not leave a voice mail and i will get back to you asap. thanks for looking.
