Neither would be relevant because it is not a "touch screen" in the traditional sense.

The iPhone uses capacitive touch sensing technology.

It senses the electric field of a finger close to a certain part of the screen, and then acts on it.

This is not a pressure issue, as the actual touch doesn't matter (its glass after all, not plastic!) but the electric field of your finger does, and thats what it measures only VERY close to the LCD itself, so just the glass and a tiny bit extra room.

Also dirt wouldn't affect it because, again, this is not about touch, but how close your finger gets to the capacitive sensor, and unless its a few millimeters of dirt or grime (YUCK!) then it isn't gonna be any hassle.
