IPhone 4s what's wrong with it?

I threw my iPhone 4s so my screen has blue and black lines all threw it but everything still works I juss can't see what i'm doing on it. What needs to be fixed and how much will it cost me?

Get iPhoto 5 instead, homie.

If it needs a new digitizer it will cost about $100 to $150. You may want to consider getting a new 4 or some other phone if that's the case.

Another thing that you could do is wait a little longer and hopefully, with any luck, it will fix itself (or at least enough so that you can use it).

Try Craigslist there's people that repair iPhones shouldn't cost more than $100 or less

I've recently read some forums where people have said a solid hit to the back of the phone will resolve those screen problems. I've never had experience with it but thought I'd pass it along in case you wanted to try it.
