Sorry to tell you this but the ability to track a cell phone user has NOTHING to do with having a GPS chip in the phone. When you cell phone is "On" it periodically transmits an "I am Here" signal to the nearest cell site. That way, you receive your calls and messages (They have to be routed SOMEWHERE). Once you are located within a given cell, it is technologically easy to triangulate your position with a fairly high degree of accuracy.
If you wish to not be tracked, TURN THE dadgum THING OFF!
