As technology advances, mobile devices are playing a bigger role in our lives. Thousands of you have been using the iPhone and Blackberry applications to post and edit content for your blog, and over 60 million page views a month of WordPress.com blogs have been on mobile devices. New smartphones do a great job with most web sites, but older phones have many problems and may not display anything at all.

Today we’re launching a couple of mobile themes that will automatically be displayed when your blog is accessed with a compatible mobile phone.

The first theme is a modification of WPtouch and will be displayed to phones with modern web browsers like those on the iPhone and Android phones. The second theme was developed from an older version of the WordPress Mobile Edition and will be displayed to all other mobile devices.

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.

If you would like to disable mobile themes on your blog, go to Appearance->Extras in the Dashboard and uncheck Display a mobile theme when this blog is viewed with a mobile browser. For more details, be sure to check out the Mobile Themes support page.
