Smartphone Safety Risk

I got a forwarded email today with a link in it to a news story about how it is dangerous to post pictures online from your Smartphone.  The GPS technology in the phone adds information to the pictures that tells the exact location the picture was taken.  So a predator could find out where you live, etc.  You can disable the function that does it to make your pictures safe.  Here's the link to the news story: http://www.youtube.com/watch?v=N2vARzvWxwY.
