I just recently dropped my iPhone 4, it still works but the screen is black. What should I do?

Have you tried completely rebooting it again and charging it?

Yea I have, and right now I'm in the process of restoring it. I'm just not sure if its going to work.

You should reset your device as a last resort and only if you can't restart it.
To reset, press and hold both the Sleep/Wake and Home buttons for at least 10 seconds, until you see the Apple logo.
