So what. If you were to location track my phone you would have found out the "TOP SECRET" information that my girlfriend and I went out for dinner last night.
However you could have easily found out the same information because; I used my credit card, we are known to the waitstaff, her older children greeted us when we returned to her house.
If I were to be doing something that required it I would take measures including no smart phones. But for my normal life I really don't care.
