title: Inputting a coordinate into blackberry Z10 via native maps
body: <p>in iphone, we can use
  maps:daddr=&amp;saddr=;
  to map directions between two points via apple native maps,</p>
  
  <p>in android we can use
  geo:</p>
  
  <p>in blackberry, if i use maps:, i can call out the native maps, with current location centered. 
  But can't get directions between two points, is there any certain syntax that should be used to retrieve directions?</p>
