As the name intimates, the new Knapsack Phone comes, surprise integrated with a knapsack. Perfect for children, the handset's real atrributes include a GPS function to locate your kids anywhere they may be (and many times it's really, really not where they should be) as well as a "crime prevention buzzer" to alert anyone to an emergency. Of course, the phone promises ease of use for even the smallest child (or stupidest adult) and you can also preset special phone numbers into the mobile's large "1," "2," and "3" buttons. The "0" button also offers instant information for any child lost or in trouble.
