3 week old iPhone 5 16gb white unlocked swap +

Hi there, I bought this iphone 5 in white from Apple Store in Victoria Sq on the day it was released. Id like to swap it for either a Blue Samsung galaxy s3+£100, or a white Blackberry 9900 bold +£200 My iphone is mint, comes with two cases and is sim free. Your phone must be the same, or at least work on vodafone. Please no scams asking me to reply to a dodgy email address, I wont reply.
