Why can't Apple replace the screen on the 4s?
Oh, they probably can. It's just that most people would rather have an instant replacement rather than waiting days or weeks for it to be done in a repair center someplace..
You do know that if you take it into Apple they do a complete replacement with a refurbished unit for a flat fee?
Because replacing the display/front glass requires completely disassembling the phone, unlike the back glass.
It would be cost prohibitive to do that in the stores.
