Settings/Location What does this mean? If I enable all of the Location options, what am I opening myself up for? I read in today's paper where the U.S. Supremes have said the police must have a search warrant before they can track someone with a cell phone. Does this relate to Locations? Can I be tracked if I have Locations enabled? Can I NOT be tracked it I have Locations disabled? Or am I completely off base here? Tell me about "Location." Exactly what funciton does this perform on my phone?
