title: iPhone link to map directions using string "current location" not lat and lng for saddr
body: <p>I know there are numerous questions about how to construct a sharedApplication link to the maps app specifying the start and end address with coordinates. I've got that working no problem.</p>
  
  <p>Has anyone found a way to link with a source address generically specified as "current location". </p>
  
  <p>I ask because the scenario I'm working on having Core Location or a UIMapView would only be necessary in order to determine the user location prior to handing off to the map app where the user locating would seem to just happen again.</p>
  
  <p>I've tried throwing UTF8'd "Current Location" and "[Current Location]" into the saddr parameter which amusingly starts from Current Montana. I've also tried simply excluding the saddr param.</p>
  
  <p>I know this is often tread territory but this particular situation wasn't covered by anything I found searching here or on mapki. Before I add the core location code I just wanted to make sure there wasn't a more limited way to tackle this.</p>
  
  <p>Thanks </p>
