I have include the mobile stylesheet and the jquery.mobile-1.0.1.min.js into the portal header. The UI changes into the mobile edition, but It looks like that the default buttons does not submit the actions (e.g. create records, or login methods). Do you have any known issues on this topic?
I am not sure I understand what you are doing, or what the problem is? Did you just change the default portal page to include the jquery.mobile.1.0.1.min.js? Were there other things you did?
