In my line of business, discovering secrets is put at a premium. If you've got information that somebody else doesn't have, you've got the upper hand. Finding out where anonymous information comes from can be very important. Caller ID has been used for years, but the use of cell phones has driven many of us crazy. I found this Reverse Cell Phone Lookup that can find the source of a cell phone number and who owns that number.

I know there are many people out there that have been looking for this type of service for a long time. I just hope the government doesn't step in and try to shut this type of thing down due to some bogus privacy concerns.
