Dropped my iphone and it won't back on?

So basically I dropped my iPhone and now it won't turn on and all the screen is cracked. But will a new screen fix it? The reason I think it will is because it is still being recognised by itunes and when I hold the power button it still dissapers from itunes too. So does this mean a new screen will fix this?

Yeah probably getting a new screen would fix it and also buy an otterbox otherwise your likely to break it again

If it's still under warranty, take it straight to apple repair.

if apple can't fix it they will give you a brand new ipad. (wow)

check apple's warranty policy.
