You need to set the meta tag for viewport to the size of the iPhone screen.

<meta name="viewport" content="width=device-width; height=device-height; initial-scale=1.0; maximum-scale=1.0;"/>

This will scale the page correctly so that you do not have to zoom in at first, and will prevent the user from scaling after the page has opened.
