An odd and annoying thing here, but may be normal.
When I view the TwentyEleven theme on WordPress.com on an iPhone with the "See it in Action" button. the content fills the screen. Looks reasonably nice, the text is readable, etc.
However, when I view my site using the same template, the pages are greatly reduced in size. Instead of filling the screen with the content alone, the content is shifted to the left half of the screen and the right hand side of the page/browser background fills the right. You have to pinch zoom to read the text.
Is this normal? Have I mucked up my theme templates? (Don't think so, as it does the same thing when I activate the original theme.) Or is there some magic going on at WordPress.com to display these template samples differently when viewed on iOS? (my sight is self hosted).
