Problems with IPHONE4

If rebooting doesn't help, then try to do a software restore. If it still doesn't work, then you will need to make a trip to the apple store

 

How exactly will that fix an iphone that has been physically damaged?

 

Things to do before taking it in. Since it only takes 10 mins to do it, might as well. If it still doesn't work, you aren't out anything. If it does work, then he doesn't need to take a trip to the store.

 

Lol
Exactly.
You broke your phone, just reboot or restore it.
That also fixes broken screens, damaged hardware etc.....

 

I've seen stranger things...

 

When you drop the phone and things starting not to work or malfunction its called physical or hardware damage.

 

Are you confident that nothing is damaged on the inside of the phone? You said you dropped it so there could be something damaged inside.

 

You were quite clear and I'm telling you what happened. There may be no scratches or dent on the outside but it's a different story inside. The shock force could have damaged a connection or one of those ribbon plugs so now your screen is unable to respond to any input. No amount of powering on or off or restoring it will help.
