"Hi, I'm Richard Goms, I'm here in Salt Lake City, Utah. We're talking about finding a person by their cell phone only. There are a number of websites available on the internet that allow you to do a reverse lookup on a cell phone. Of course many people nowadays don't even have home phones anymore, so they aren't going to show up in the regular white pages. You can go to a reverse mobile site and type in the phone number and pay a small fee and they will give you whatever information you're requesting. In addition, you could just type the phone number into say a Google search engine and it will bring up websites that tell a little bit about the person that you're searching for."
