I was recently talking with a friend about my Mobile HotSpot Tracking idea. He pointed out that some phones are GPS enabled. When a cell phone manufacture claims they are GPS enabled it’s likely that the GPS they are referring to is not satellite based. Cell phone towers are used to triangulate the position of the phone. The problem with this is that I don’t have a way to access Mobile Phone Company backend to mashup with Google Maps API.

Engadget.com posted an article regarding tracking down a kidnapped baby who was in the car along with the cell phone when it was stolen. The process for acquiring the position for the cell phone was at best two-and-a-half hours. Not so good for real-time tracking.
