PLEASE HELP! Screen Insanely cracked! Instinct HD...

I love my Instinct HD it is by far one of the best phones I've owned. Earlier today I dropped it and it landed screen down in the parking lot. There is a huge spider web crack but the phone still works just the same, I wondering if it is possible to replace the screen instead of having to replace my phone for 50-100 dollars? I don't want to have to get a new phone even though the phone works fine! But I also don't want to have to look at the hiddious crack in the screen every time I go to make a call or send a text!

PLEASE HELP!
