On full-screen iPhone web apps »
A great article from Neven Morgan about designing/developing full-screen iPhone web apps. I should note:
I mean that a page can specify it should be shown without the navigation bar at the top and toolbar at the bottom (the status bar is there to stay, and you can’t change its color).
There is actually some control of the status bar, as noted here. Also, most of the methods here are included by default with the jQTouch framework.
