IOS 6 blank page

Hi all, I've updated my iphone to IOS 6 but I've a problem with jquery mobile.
I develop a website with:
- jquery.mobile-1.2.0
- jquery-1.8.2
and when I try to load the site, Safari show a blank page with "0" and the link in the address bar become javascript:0. I have tried with
http://jquerymobile.com/demos/1.2.0/
and it return blank, too!
Any suggestions?
thanks,

len
