Part plugin, part theme, part iPhone application. WPTouch is a plugin from author that turns your blog template into an “iphone app” style theme optimized for smartphones. It allows you to offer a faster, more user-friendly version of your site to any iPhone or iPod Touch visitors without affecting your normal blog theme.
Users also have the option to switch between the WPTouch version and normal version of your theme if they prefer the high-rez version. Your WPTouch version comes complete with AJAX loading articles with effects and real time commenting . The theme is complete with all standard WordPress features and templates, such as a links page and an archive page. It also has native social bookmarking support and Flickr RSS support.
This plugin/theme is a great alternative to coding a mobile option into your current theme or even offering an alternate url for mobile visitors. As it is all under 56 kb, it doesn’t slow down your regular visitors at all.
I do realize that WPTouch is a great plugin for WP and make a post about it on my blog : http://bloggermaniacs.com/blogging/making-your-wordpress-blog-ready-for-iphone-ipod-android
