Control freaks rejoice - now you can know for sure if your teenager is really at the library studying. TeenArriveAlive works with Nextel's GPS service to locate your child, right down to the street number.
If it's employees you want to track, you can use Nextel's Mobile Locator.
You can also track pets with a dog GPS collar, which could be very useful since most dogs don't have cell phones yet.
The locator services are different from the Telenav service which provides audio and visual turn-by-turn navigation through Nextel phones. If you want a full-featured Telenav enabled phone, you might want to wait for the new 7520 Blackberry phone, due in the fall.
