I heard that when you take a picture on an iphone there is extra content in the .jpg that has the location or something, how do you access this? Also is there a way to see the data google collects on you? I set up gmail in my iphone and playing around with gmail on my PC one day and it had a map of all the places I went to when I was using the gps on google maps on the iphone. Kind of scary but novel at the same time seeing all the places you go.
