Mobile visitors greeted by WPtouch will get easy access to posts, pages, and archives. They’ll get fancy AJAX commenting and post loading. If you are using a custom header image, it will be scaled to size and displayed at the top of your blog. When viewing your blog on other phones, the focus will be on loading the blog quickly while displaying the important information about your content.
As you'd probably guess, loading up acurrie.wordpress.com in Opera Mini yields not the fancy iPhone version on the left but the much nastier old-school one to the right.
Oh well, beggars can't be choosers...
