jQuery Mobile activating geolocation on mobile devices

jQuery Mobile activating geolocation on mobile devices

Hi,

a very strange thing appears when visiting sites/apps using jQuery Mobile with an iPhone4S (iOS6.0.1).
The geolocation seems to be automatically activated, shown by the GPS-arrow in the status bar - which drains the battery pretty fast.
Tested with jQuery Mobile 1.1 and 1.2, and also reproducable on the demo website http://jquerymobile.com/demos/1.2.0/

I can't find any relevant functions in the code - what can cause this behaviour?

(It does NOT happen on http://jquerymobile.com/demos/1.0.1/ )

Thanks,
Toby
