title: Accessing location information on iPhone from web application
body: <p>Is there any way for a web application to access the location data of an iPhone without the installation of an additional iPhone client app?</p>
  
  <p>If not, the next best thing would be if any can recommend an existing native app, preferably free to the end user and as lightweight as possible, that <em>does</em> expose this information to Mobile Safari.</p>
