Just wanted to pass some information that I read yesterday on to you. It is important that we keep our cellphones clean. Everytime that we place the phones to our ears, skin oils, dirt and grime are transferred to the phone. Then... if the phone has not been cleaned with a mild soap, all of that oil, etc is returned to the skin the next time that we send or receive a phone call. The less often that we clean the phone, the more nasties are deposited onto our faces causing additional risk of pimples, etc.
