We use  http://www.telenavetrack.net

You can track from your i95,i730, or your computer and get maps, street
address, speed of travel, and there are many settings to adjust how
often the phone sends back data. The more often data is sent, the more
accurate readings of speed etc. Great for employers and parents of
teenage drivers.

Gook luck,

Mike
