If you’ve been looking for a Nexus 4 in a retail location, and for some (probably valid!) reason won’t buy it from the Play Store for the cheaper price, Google has you covered. They released a tool using the Google Maps API to show you the closest Nexus 4 retailers to your address.
Right now, it’s only showing T-Mobile stores. Keep in mind that other stores carry the Nexus 4, like Best Buy, so if you don’t find a T-Mobile stores with one in stock, you still have hope. Hit the source link to explore the locations around your area!
