Map for blackberry Tablet Os

This is an off-the-cuff example with MapQuest:

                import com.mapquest.tilemap.Size;
             import com.mapquest.tilemap.TileMap;

          var mapkey = "YOUR_MAPQUEST_KEY";
          var mapWidth:Number = 1024;
          var mapHeight:Number = 600;
          
          var map:TileMap = new TileMap(mapkey);
          map.size = new Size( mapWidth, mapHeight);
          addChild( map );

That should give you a map object the full screen size on the playbook

Though they've discontinued support, Google's AS3 maps implementation works fine: http://code.google.com/apis/maps/documentation/flash/

For devices where their maps don't work (like iOS), we've successfully used MapQuest's maps: http://developer.mapquest.com/web/products/featured/as3-flex-flash
