IPhone 3G screen gone black

I recently dropped my iPhone and now the screen is completely black. I can hear people calling and sending messages and when I go to plug it in to charge, I can hear it charging although the screen is black so I can't use it. I have also tried to reset it by pressing the home button and the lock button for 10 seconds, It's still black.

Any suggestions?

Sp you turned it off now turn it back on and i f that dosent work repllace it or i don't know if the iphone has a battery or something but take the battery off of the phone and out back on and turn it on

Upgrade your phone, hold it for 30 sec home button and lock button also try holding the volume button as well, get a repair or talk to a genuis
