Engadget is reporting that Sprint is working on a new service for its LG Migo limited use cellphone for kids called chaperon. Using the GPS chip already within the phone, parents will be able to track the whereabouts of the phone for a small fee ( $10-15 a month). Parents will be able to view a map of the kiddie phone location using either their phone or a website and will also be able to set up a georeferencing feature so that they can receive text messages if their kids enter a "forbidden" territory. While this is marketed at parents tracking kids, I am willing to bet many spouses would like it in order to limit who their other talks to and track where they go.
