That's the cool thing about iPhones. If you are in warranty and you go to an Apple store, going by experience, they've been able to replace my phone with a refurb (and I was traveling on business when it happened once), give me a loaner while they had my phone for repair another time. Of course it's because of the number of stores they have that they can do it but still support second to none.
Actually
@CowboyCombat8557... Have you contacted a UBREAKIFIX in your area?? That is one positive that they Samsung uses them as an authorized center for warranty support. Contact one and if they can do it under warranty, if they don't have the part in stock, they can order the part, call you when it's in and make an appointment to have them replace the screen that day... worse case you go shopping for a few hours and come back.
That was one concern with going Android but fortunately didn't have any warranty issues.
