I'm just a few weeks into figuring out mobile sites and found this extension for my Joomla 2.5.6 site. I liked the use of widely accepted JQuery and JQuery Mobile. I downloaded and set up Jtouch on my dev site, then got it running on the production site. I ran into a problem, which is promptly resolved after a posting to the support forum. Jtouch is still a work in progress; I'm hoping for out-of-the-box support of more major extensions, especially Mosets Tree and JEvents. I strongly recommend Jtouch.
