Iphone screen will not work?

My Iphone screen will not work. Everything else works EXCEPT the actual touch screen part. Like, I can see that everything else works too. And it looks absolutely normal. What happened! And what do I do!

One of the first things that Apple had me do was to restart my phone. This is easily done as you hold down the square button at the bottom of the phone (below the screen) as well as the bottom on the very top right of the phone at the same time. This is the same as pressing the menu and middle button on your iPod. It does a simple restart of the iPhone and that alone may due the trick. If that does not work then you have to go a little deeper with the restart and do a restore of the phone. Fear not, you are able to backup your iPhone in this process so when it is restored you have the backed up file still on your computer with all of your information.
