You have a lot of options for customizing your iPhone 5. You can get a completely refurbished phone with a new screen and rear in almost any color combination you'd like or a basic used phone, only available in black or white, which will still be in great condition with minor scratches!
If you'd like a used phone then simply choose "Non Refurbished" for the front and rear. If you'd like a refurbished phone then choose refurbished in the first box and then your color choice for the front and rear.
