Instead of launching a separate child-friendly handset or just farming out the idea altogether, Sprint is launching their new "Family Locator Service," which involves software to enable existing Sprint phones for tracking. A total of 28 GPS-enabled Sprint phone models can be located with the service, and a bit of downloaded software is compatible with 17 of their phones to track up to four handsets, and even display a child's location on a map. The service is $10 a month, and it's based on software by WaveMarket Inc., which can also be used on your PC. Sadly, we missed the press conference, which somehow managed to involve Sprint getting all defensive about this being a "Big Brother" tool, and stating: "It's not about tracking. It's not about monitoring." Uh, right.
