HTC One X 32GB White (Three) SWAP for iPhone4/iPhone4S !

Looking for a SWAP?? I recently upgraded from an iPhone 4 to the HTC One X but I am looking to go back to the iPhone as I prefer iOS to the Android OS. Handset is in excellent condition and only 1 month old (11 month warranty remaining). I still have the box, manual, charger and ear phones. Ideally looking for an iPhone 4S 16GB or a newish iPhone 4 16GB on the Three network, Contact me if interested.
