Mobile Safari for iOS and Google Chrome for iOS ignore viewport settings on .mobi domains. If you don't specify a viewport for content served from a .mobi domain the rendering engine assumes a certain viewport other than for content served from a .com domain. If you define your own viewport it will be ignored. See this article: http://www.davidroessli.com/logs/2010/04/safari_ignores_viewport_mobi_domains/ e.g.: we deliver the exact same content from http://www.caruso.mobi and from http://www.carusocarsharing.com On the .mobi domain you can't zoom out to see the entire page. On the .com domain you can! You can try it by yourself on your iPhone here: Everything OK: http://www.carusocarsharing.com/static/css/test.html clientWidth: 980 clientHeight: 1091 window.innerWidth: 980 window.innerHeight: 1091 screen.width: 320 screen.height: 480 **************************************** Doesn't work as expected: http://www.caruso.mobi/static/css/test.html clientWidth: 320 clientHeight: 356 window.innerWidth: 320 window.innerHeight: 356 screen.width: 320 screen.height: 480

In the meantime we redirect from http://www.caruso.mobi/static/css/test.html to http://www.carusocarsharing.com/static/css/test.html Not even then does the viewport work as expected! But if you directly go to http://www.carusocarsharing.com/static/css/test.html it works as expected (you can zoom in and out properly with the magnifying gesture on the iPhone / iPad)
