I'm trying out your HelloWorld mobile tutorial on OSX 10.7.5 (Lion). Just created the project and clicked the run icon.
The iPhone simulator is not being displayed.
Instead, I get a webpage with a button in the top right corner, a black bar across the top with some text in the middle that says "Page 1", and a grey area beneath covering the rest of the web page. (These elements are probably supposed to be displayed in the iPhone simulator.)
What do I need to do to have the iPhone simulator displayed instead?
For best results, use the Firefox browser..
