Location Based Technologies has released its latest PocketFinder Location software, now in the form of an iPhone app. By using the program, a person's friends and family should be able to view the location of their iPhone worldwide, from any smartphone or computer. Included in the app are alert zones, which allow customizable alerts to be sent out whenever a user leaves a specified area.

Alternately, speed alerts can be sent if a person is exceeding a pre-programmed velocity. Travel history can be kept for up to 30 days. Available to download for free from the App Store, PocketFinder Location is intended only for the iPhone 3G.
