Wired on GPS-Enabled Smartphones
Two articles from the February 2009 issue of Wired look at location-aware applications for smartphones with built-in GPS (or other means of determining location). Inside the GPS Revolution: 10 Applications That Make the Most of Location is a list of applications — for several platforms, including the iPhone, BlackBerry and Android — ranging from speed traps to astronomy. I Am Here: One Man’s Experiment With the Location-Aware Lifestyle looks at the implications — especially the privacy implications — of living with a GPS-enabled mobile device:

Because iPhones embed geodata into photos that users upload to Flickr or Picasa, iPhone shots can be automatically placed on a map. At home I searched the Flickr map, and score — a shot from today. I clicked through to the user’s photostream and determined it was the woman I had seen earlier. After adjusting the settings so that only her shots appeared on the map, I saw a cluster of images in one location. Clicking on them revealed photos of an apartment interior — a bedroom, a kitchen, a filthy living room. Now I know where she lives.
