Black tmobile iPhone 4s 16gb £350 OVNO *

I am selling my black iPhone 4 S 16gb due to having a new contract, 6 months old few scratches, nothing major. - proof of purchase - USB, charger, headphones and pin (to get sim out) all in box. - It is on Tmobile and I do not think its unlocked. No ridiculous offers or sending abroad! If pictures are wanted I will have to send via hotmail due to not knowing how to work my iPad. Thank you!
