Replacement Woes

[strra]

well, the inevitable has happened. my keyboard isn't working right... but this isn't another complain thread; i actually have a question.
the phone fell about 2 feet and has a rather noticeable ding on the chrome. i know that the fall didn't mess up the keyboard because i used it for a long time afterward and the keyboard is just now starting to act weird. so my question is: will the employees at sprint see this and still claim user damage to the phone and charge me for the replacement?
