There are three types of touchscreens: resistive, capacitive, and infrared. Resistive phones have two layers and when the top layer is pushed onto the bottom one an electric current senses this and calculates the location. Capacitive have currents coming from the corners and when changed it's calculated. Infrared use heat sensitivity and optics.

no as to my knowledge and research in the past a touch screen phone will not work underwater. A way that you might be able to get around that is to cover your touch screen phone with a clear or water proof covering so that way your phone won't get wet.
