My iphone fell and it would not turn on at all

The phone fell and turned off, every time i try to turn it on! The apple logo would show for 5 secs but it would shut down again! I and when i try to connect to a computer it won't connect! It is an iphone 4!

Well obviously you damaged it and I don't think a messageboard will fix it. Take it to the apple store to see what's wrong with it.

Try holding the on button and the home button for 5 seconds i think that's meant to do something.
