The screenshots in this article are deceptive. What the meta tag does is make Safari always look how it normally looks when you scroll down from the top of a web page. So, in portrait mode, there will be a small top bar showing the website URL. In landscape mode, there will be no top bar at all. Here's a screenshot from the other commenter's website on my iPhone:
have you tried it? don't be concerned it is very easy for a user to get the ui back by scrolling up. If you haven't hit any sites yet try ours here http://www.freeriderhd.com
before this change, playing our game was a real pain on iPhone this was a much needed improvement.
