This plugins displays a location based map on your sidebar. It tells visitors to your blog exactly where YOU are!
This plugin takes advantage of new GPS capabilities inside of the browser on your mobile phone.
If you've added the Smartphone Location Lookup widget to your page and if you have an iPhone, or something new like an HTC Dream, every time you refresh your site on your phone, you'll update a map in the sidebar telling your stalkers/readers where you are.
You can choose from either Google Maps, or Bing Maps to display where you are and have all the choices that these two map providers offer (marker labels, etc).
You can update your location manually from the Widget too if your phone doesn't support GPS, just expand the widget and amend your latitude/longitude.
In addition, most web browsers now have the same GPS capabilities, so if you allow Firefox/Chrome/etc to record your current location, it'll update the map.
