Since using WordPress to host my blog, I have only begun to scratch the surface of what it is capable of. Recently I installed a plugin to my WordPress blog called WPtouch. What WPtouch does it add a very easy to use interface of your blog to any mobile browser. This is great if you happen to access my blog from say an iPhone, Droid, or Blackberry. WPtouch renders the blog in a mobile site. However if you do not wish to see the blog in a mobile version, there is a button on the bottom of the page to turn the view on or off. So if you did want to see the full site on your mobile device, you still can. WPtouch is also very customizable on how much you want to tweak the colors and view of the mobile version.
However if you still access the WordPress site from a regular browser on a computer, it will display as normal. WPtouch is only for mobile browsers. So if you happen to use WordPress and want a quick way of having a mobile version of your site, you may want to check out WPtouch.
