When viewing mobile themes on the iPhone, this works perfectly. On Android phones, the theme appears to be showing the page with the text in the center and then the browser moves the text out of view and the page moves towards the left alignment.
You can see this here - make sure you either turn user agent to Android or choose the "use mobile theme" on the bottom of the page.
Choose an article. You'll see the difference in view on the iPhone and Android. I can't be sure if it's the plugin or the theme that is causing this anomaly.
