“Whatever the case may be, you want to find out all the information about that mysterious phone number as you can. In order to do this though, you need to be using a legitimate reverse cell phone search site. These sites will provide you with very detailed reports based on the number that you submitted.” - By Isaac Merrow, Ezinearticles
One such service that can trace all calls including cell phones and private numbers is reversephonedetective. Not only is it a great reverse phone look up service, it provides an up to date report on the caller.
