"Free" reverse cell phone directories online include National Cellular Directory and Spy Dialer.

Spy Dialer lets you to listen to out-going voice-mails of cell phone numbers. You might get lucky enough to hear one that mentions the name of the cell phone number owner in the message. Recordings rarely mention addresses.

Facebook is another option to help you locate owners of cell phone numbers. Search for a phone number at the top of a Facebook page screen and then press Enter. If it's been added to a Facebook profile, the name of the owner will appear on the top of the results list.

On some other sites, to get the phone user's name and address, you might be asked to pay a one-time fee, often about $15, or a yearly fee of $40 or more to cover unlimited reverse phone searches. Reputable sites won't charge for searches that come up empty.

Making cell phone numbers more accessible in the future may seem logical to some, but it's viewed as an invasion of privacy by others. In early 2008, Intelius announced it had created an online directory of 90 million mobile phone numbers, approximately half of those in the United States.

However, faced with cell phone users' privacy complaints and a potential lawsuit by a wireless phone company, Intelius quickly discontinued the service.

Of interest, a recent review of studies dealing with cellphone exposure and male fertility suggests that men who carry their cell phone via pockets may harm their chances of conceiving a child with their partner. Men who didn't carry cell phones in their pocket discovered that 50% to 85% of their reproductive cells were able to move normally towards an egg. Learn more from Philly.com.
