I tried building an app with jQuery Mobile and the performance was horrible. Whole sets of features didn't work. I spent more time trying to get things working right than I did building the actual functionality. I had a lot more success in Kendo Mobile. If jQuery Mobile wasn't backed by the jQuery project, nobody would use it because it isn't that good. It's slow, buggy, and broken. Maybe this release fixes that, but I doubt it.
