I\'m hosting my website using Google App Engine. It\'s a pretty simple website, but I\'ve got some javascript drawing to a canvas element, which I\'m trying to test on my iPhone
As of March 2013 - the "address" argument has been renamed to "host" - (at least for Python version of the app engine)
This isn't anything specific to your OS. By default, the App Engine dev server binds to the loopback interface, making it accessible only to your machine. If you want to access it from other machines, you need to pass the --address=0.0.0.0
flag to the dev server - which you can do in the launcher's preference pane.
