title: Location Services and Settings prior to iOS 5
body: <p>I have a quick question is there a system call I can make that will provide an alert with the option to go to settings in case location services have been disabled on iOS versions prior to 5? </p>
  
  <p>As far as I know there is no URL scheme for the settings app before 5.0. </p>
  
  <p>Any ideas? </p>
