I have a Space Gray iPhone 5S. I have noticed some screen interlacing problems with the screen, and from what I've read, this is a somewhat common problem with the 5S. Seeing that I can probably get it replaced with a new phone (assuming I don't go to a store with the new machine that replaces the screen..), do you think it is possible for me to get a Gold iPhone in place of my Space Gray one? Has anyone heard of this with any other iPhone? Getting a new color when replacing it?
