Information came to me today in a video with a warning of taking photos, especially of children, and sending them to a social networking site. This can be dangerous as the location of your camera can be determined by stalkers through the location services on the phone.
To help protect yourself on your iPhone, go to 'settings,' 'location services,' and on 'camera' click 'off.' Hopefully, this keeps your camera from giving your location.
Stay safe with your technology!
