Constant hiss from ear piece

[wizdawg]

Has anyone else noticed with their touch, that there is a hiss sound that comes out of the ear piece? It's fairly quiet and not too noticeable when talking, but quite noticeable when there is no talking or a pause in talking. Now that I know its there I can even hear it while I am talking now.

My Razr on U.S. Cellular is dead silent.

Is this normal or is my Touch defective? Its only a few weeks old.
