Iphone External Screen Dropped IPhone, No Crack But Touchscreen Doesn't Work. A Few Days Passed Warranty...?

Dropped iPhone, no crack but touchscreen doesn't work. A few days passed warranty...? - iphone external screen

I had my iPhone 3G today and the touch screen is completely insensitive. The keys are working outside, and I tried resetting the phone several times - no luck.

My one year warranty on 7 expired. AT & T said Apple about this call and they act with him, because the guidelines for safety ..

I had cracked even before the screen, but I had to be replaced by a statement of the company. Is there a way for them to know?
