For starters, you'll no doubt find most of free lookup services out there to be a complete waste of time.

This is because free reverse cell phone number owner search directories are made up exclusively of information that's available in the public domain - social networking sites (MySpace, Facebook), bookmarking sites (Twitter, Digg, etc.), forums, discussion groups, bulletin boards, contests/sweepstakes, blogs, and personal sites - and as such, are likely to be out of date, incomplete, and inaccurate. They are most likely to contain information on owners of land line phone numbers but not private, unlisted cell phone numbers.
