I’ve talked about this subject a couple of days ago in a WebTuesday meeting, here are the slides of the presentation:
http://www.slideshare.net/akosma/webtuesday-mobile-web-applications-framework-overview
I talk about the following frameworks / technologies:
- iUI
- jQTouch
- WebApp.net
- iWebKit
- SproutCore / Cappuccino
- Yahoo! Blueprint
I personally have used iUI, and then later jQTouch, which I literally fell in love with.
