I wonder if you shut your phone off while traveling if it could still track you or ping off towers. I do have the no tracking option positioned to off. I have, for instance, seen notifications for people on FB that says blah blah is currently at such and such a place or they've been there. I guess that's cool if you want everyone on FB to know where you are at but I'd rather not....nor would I want them to know where I've been either. I guess if I wanted to go on a super secret trip someplace where no one but one trusted individual you want to let know in case of emergencies, I'd give them the phone to carry around while I went in the opposite direction...lol.
