i know that with verizon when your screen cracks you can do a replacement phone for 50.00, i don't know if alltel has this, but you might check with a rep there. Just make sure that when you call that you don't give them your acct number so they can't notate it, also call from a phone that is not on your alltel account otherwise it will auto populate your account on their screen. Just ask them if you cracked your screen what is the replacement policy, you might call twice just to make sure, you know how customer service is nowadays.

edit
you might be able to get ahold of a bricked phone online, every once in a while you see them on ebay for spare parts, if you cant get alltel to play ball.
