Mobile Web Development Frameworks

I am looking to see if 开发者_StackOverflow社区anyone is using Mobile Web Development Frameworks, examples of these include:

• Sencha Touch
• jQuery Mobile
• iWebKit

Has anyone used any of these or anything similar? I really want to gauge if the mobile web community on StackOverflow are using Frameworks.

Cheers, J

I've used the jQuery Mobile stuff in a widget I've done for Nokia, and I preferred to use it over the Nokia alternative "Guarana". I chose to use it because I was familiar with using JQuery and Themeroller, no other reason.

Sencha Touch and jQuery Mobile have some questions being answered here.
