Dropped my iphone

I dropped my iphone today and the touch pad won't work now? It wasn't a big drop though, and when I double press the little button at the bottom my ipod still works and I can still tap play and fast forward and etc on the touch pad

I think only the bottom of the touch pad is not working

It just happened 5 minutes ago

Will it fix itself soon or is it broken for good?

If so can it be repaired?

ok I turned it of and turned it back on again and I'm now on the main screen but the bottom half of my touch screen still does not work, but the top half does work

Take it to an apple store...

.... and don't mention that you dropped it.

Is there any PHYSICAL damage? If no, take it in, DO NOT SAY YOU DROPPED IT, and tell 'em the bottom part of the screen doesn't work. They'll probably swap it out.
