I'm on an EVO using Dolphin Browser.

...and you're totally right about jQuery Mobile causing suckage. I used it for a couple features and I'm now ripping it out in favor of a little handrolled solution I built. I even replaced the jQuery core library with XUI because it's even smaller has most of the goodies I use 99% of the time.

For everything XUI doesn't have, I really like XUI.extends in its simplicity better than the jQuery plugin architecture. Super easy to add whatever else you need.

Performance is night and day better now.
