nokia lumia 900 looking to swap for iphone 4/4s or other phone !

Nokia lumia 900 newest model. black in colour. on vodafone. have box and accessories, has a few tiny scratches on screen where it was in my bag. but nothing u can notice. The reason im looking to swap is because i dont really like the phone, its a great phone really fast and does alot but its not for me. I would prefer iphone 4/4s but am willing to consider other genuine offers. only vodafone or open phones please. NO stolen phones etc. Im not interested in cons. Not looking to sell sorry as cant deal with all the hassle of not having a phone and then having to find a new one. TXT ONLY PLEASE. I WORK ALOT AND WONT BE ABLE TO ANSWER CALLS.
