iPhone and iPad store the actual position in a file?

I am overwhelmed! What news!
All those guys who criticize Apple now: Don't you have more important problems? Do you know that pretty much all the smartphones do that? What's the deal anyway? Somebody could eventually see where I was if he got hold of my phone or could access my computer? Wow, unbelievable! All that somebody can see in such a file is what most people know anyway: I get around quite a lot. What do you want to do with that information? Send me tailored advertising email? I have a rigorous filtering system you won't have any luck with that. Send me a list of great restaurants for the places I've been to? I'd appreciate, eventually I'll try one the next time I will be in that location. And I'll even let you know so you don't have to check the logfile...
People are a bit paranoid. They publish every fart they make on facebook but then they get worried about a phone logging positions. All that logfiles tell anybody by the way is that the PHONE was there. I do not see what that has to do with the person.
