iPhone dent

Hi there, my only concern is that my iPhone has a dent from falling off a height of a 5'6" person from his knee, since it fell of my couch which its seat is until my knee and that is my height, height aside, it looks really ugly, although it is not noticeable from about 2 meters, but when someone holds my phone it can really be felt. the dent is in the side by the upper left of my phone. where the earphone jack used to be on previous iPhones. Is there any way I can have this repaired? Or replaced? I'm willing to pay, as from what I have read in other discussions regarding their dents. But I have no luck in finding an online document here on the apple website regarding how much I would pay or anything related to a device replacement. I've had my phone for 29 days and am still eligible for a warranty. Please help, sorry if I am a bit too lazy to look for the document my self as I have tried but all I keep finding is the repair, not the replacement.
