WP7 JQuery Mobile Multi Page Template, "Error Loading Page"

This simple JQuery Mobile multi plage template:

http://jquerymobile.com/test/docs/pages/multipage-template.html#/test/docs/pages/multipage-template.html

Does not work. When you tap the button to "Show page two" you get the "Error Loading Page" dialog. The output window says this:

XMLHttpRequest.open x-wmapp1:/app/www/index.html

I tried using 1.3.0, and I also tried updating phonegap-1.3.0.js to phonegap-1.4.0.js, but it did not resolve this issue. I see that release 1.4 is due out tomorrow (January 30, 2012, I suppose is what Jira means by "tomorrow"?). Could it be that I need to wait until tomorrow and then install the full phonegap 1.4 in order to know if 1.4 resolves this issue? Or is updating phonegap-1.4.0.js enough?

This PhoneGap for WP7 is getting SOOO close, and many people I know are very excited to use this! Great job Jesse.
