[OpenLayers-Users] Problem to show ways in vectorlayers (mobile)

[Jan Tappenbeck]

hi !

i want to show way-elements (data by overpass) and define by vectorlayer.

here the link: 
http://www.tappenbeck.net/osm/maps/deu/mobile2012.php?id=9512#mappage

first you had to add the layerswitch (top-left) and move the map little. 
left-top of the roundabout is a park with dark way-lines (on a  pc).

but my problem is that the ways will not show on mobile device (htc 
desire - android-browser).

the sourc you can find at 
http://www.tappenbeck.net/osm/maps/js/hms_002_overpass.js

did anyone have a idea why will not show and a alternative ??

regards Jan :-)
