I saw something pretty creepy (take note if you have kids). Pics taken with a iPhone contain .xif data. This data can be read and traced. Here's an example.....say your daughter takes some cute little self pics at home for an online social networking site. Someone can read the exif data and read personal info and gps coordinates of where the pic was taken. Then use something like Bing maps and track exactly where the pic was taken. I saw an example of a pic, name, age, address and even a birdseye view of the house. You see how this could be bad?
