Trying to remove location tracking from a cell phone is essentially impossible; they're capable of using a system called Assisted GPS which when GPS isn't available, can use things like WiFi signals to help determine where you are; http://en.wikipedia.org/wiki/Assisted_GPS#Description
Even if you were to build your own cell phone or dig out an old brickphone without this capability (thanks to the FCC's efforts, basically no cell phone made after 2005 is without it), you can still be triangulated by the network with fair accuracy.
At this point, The Only Winning Move Is Not To Play.
Right, this was a requirement so if you dialed 911 the emergency responders know where to find you even if you didn't know where you are. It is called e911 or enhanced 911.
