Cracked Screen

[b4u2]

Dropped it one day on concrete with TPU rubber case and it still cracked it is cracked in the lower part of the screen right thru the menu button. I just ported out of Sprint and switched to verizon. I was thinking of selling this phone but wondered if I could replace the screen myself? The crack is not on any of the visible part of screen and does not affect buttons. I have ETF due at Sprint and need to try and cover some of the cost.
