So I bought a 32GB white iPhone 5 yesterday, but had to exchange one because of a light leak and then I had to do an exchange another because it had scratches on the screen out of the box. Now I've realized that I need a 64GB version to hold all of my stuff. Do you think they will allow me to do another exchange or will they say I have done too many already? None of these have been through the Genius Bar, they have given me new sealed boxes with each.
