I downloaded the BlackBerry 10 jQuery Mobile theme and I wanted to try how it works on the Dev Alpha.
I created this config.xml
<?xml version="1.0" encoding="UTF-8"?>
<widget xmlns="http://www.w3.org/ns/widgets"
xmlns:rim="http://www.blackberry.com/ns/widgets"
version="1.0.0.0" rim:header="JQKS">

<description>An app to test jquery</description>
<icon src="img/generic_81_81_placeholder.png" />
<content src="index.html"/>
<feature id="blackberry.invoke" version="1.0.0"/>
</widget>
and I placed it on /kitchensink
Then I packaged /kitchensink and loaded on my dev alpha, but I get this when I launch it:

I can press OK, but the application is frozen.
If I load it on my local webserver, and browse from the dev alpha it works, what’s wrong?
In order to make it work, you have to update to the latest 1.0.3.8 SDK.
I had 1.0.2 and it didn’t work.
