Anybody have a phone with an image I can sample?

The report's authors examined in detail the rapid spread of location-based services, which have spread in large part due to the growing smartphone market. Today's mobile devices and their accompanying applications tap into a phone's GPS or use Wi-Fi triangulation to append geotags, or locational information, to the items recorded with the phone, whether that's an update posted to Twitter, a photo uploaded to Flickr or a video sent to YouTube.
A major concern with these types of applications, say the researchers, is that many consumers don't know such information is being shared, especially on a such a large, public scale. For example, Apple's iPhone by default embeds high-precision geo-coordinates within all photos and videos taken with the internal camera unless explicitly switched off in the phone's settings. The accuracy of these geo-coordinates "even exceeds that of GPS," warn the researchers, regularly reaching "resolutions of +/- 1 m in good conditions and postal-address accuracy indoors."
