Does the iphone work by the warmth of your finger tips or is it just your skin?

http://electronics.howstuffworks.com/iphone1.htm tell me if this helps. better yet hit my score so it can go up! :P

No it uses an electronic field to since your touch.

If you want, you could go look up more information about the iPhone on the Apple website.

It would be dificult for me to answer that question because one of the only places I sweat are my palms but I would say your skin.

Good question. I’ve tried using a pencil eraser and it didn’t work. I wondered the same thing

Amazingly, I can wear my broken in leather golf gloves and my touch registers on the iPhone’s screen. It was a nice trick this past winter.

I have used my nose and thumb to zoom out.<———I was driving again.

Skin works, though I tried a dog paw to no avail. When I bike I have to use my nose to unlock it b/c of my full fingered gloves…
