Did you know that taking a picture that was created with a smart phone may have GPS information in it, and posting it on a social networking site a person can scan the picture for the GPS info and it will provide exact location information as to where it was taken?
Consumer Affairs reported on this about two weeks back. Not only that, they said never put your home address on a GPS. You know where you live, and if you use it on vacation - coming home just put something from in the town you live in. You know how to get home from there for heaven sake!! Additionally, you need virus protection on some of these new phones. Anything can be traced back to your computer, too. So be careful not to exploit your family and friends. You are traceable!
