My iphone screen has cracked?

I bought an iphone5s about a month ago… It dropped from about chest height and unfortunately landed face down. The whole screen is shattered.
How much would it take to fix it?
And, i noticed from the beginning the phone had malfunctions… I'm on warranty. So I'm entitled to a new phone if i trade it in.
But will apple accept a phone with a cracked screen?

I believe if you are paying the extra for Applecare it will cover anything but loss or theft.
