Iphone 4 - As new condition -

I have my sale my iphone 4 8gb in black. I know it works on t mobile and orange but not sure about other networks as i do not have any other sim cards to try in the phone. It comes with box, charger, manuals etc and brand new sealed apple headphones as i never used them. It is in perfect condition and been well looked after. I am only selling as i am upgrading. No timewasters or scammers please. Any questions please ask....
