This came just in time - for more inspiration don't forget to check out Mari Sheibley's website http://mobile-patterns.com/ - shows the best patterns from the top apps, organized by pattern type.
Neat, but I want to be able to move elements around. For example, I want the little arrow here ( http://i.imgur.com/ngHiG.png ) on the right side - or gone - and changing that with CSS took me about 45 minutes the last time I tried.
You can change or remove icons by assigning CSS attributes to HTML elements when building your application. Removing the "ui-btn-icon-right" class from that button removes the arrow icon.
Unless I've misunderstood what you're trying to do.
