I found one great company called wherify.com , but the service is .95 for only 200 units...units being used for incoming/outgoing and tracking online where user of phone is located.That seems a bit steep. Anyone out there have any knowledge of other companies? It doesn't necessarily have to be a phone/gps. It can be a portable gps. As long as I can go online and find out where the device is at that moment and/or where it has been.
