And of course by “SDK” I mean an Apple SDK that consists of a single HTML page with half a dozen snippits of HTML.

Nonetheless there are some good tidbits there.

I was wondering about some event stuff and here is the general event info:

Gesture	Result
Double tap	Zoom in and center a block of content
Touch and hold	Display an information bubble
Drag	Move the viewport or pan
Flick	Scroll up or down (depending on the direction of the finger movement)
Pinch open	Zoom in
Pinch close	Zoom out

Remember, since there is no mouse, hover events will not work.

You can have the iPhone make calls for you from HTML pages using

in the URL like this:

An iPhone specific CSS can be applied using the

attribute in the element - which most developers probably ignore.

<link media="only screen and (max-device-width: 480px)" href="iPhone.css" type="text/css" rel="stylesheet" />

Also of interest is the viewport meta tag that lets you tell Safari on the iPhone how to scale and zoom your content:

<meta name="viewport" content="width = 320" /> <meta name="viewport" content="initial-scale=2.3, user-scalable=no" />

For lots more good info check out the recent post on Ajaxian and the google group.
