Wasn't the iPhone Multi-touch?

No, the multi touch functions using applications such as Safari and the Picture Viewer. When you place two fingers on the screen and spread them apart to zoom in on a photo or a web page, that's using multi touch.

Ah, that makes sense. Any word if multi-touch is going to be extended to all the core applications on the iPhone?

Technologically, multi-touch capability exists within each app, but apparently Apple thinks registering all touches, no matter what else is going on, makes the interface harder to use. Simultaneous taps/button-presses don't seem to be part of the interface model.

I'm sure that many of the apps will get updates to their interfaces; some of these updates might allow for a fuller use of multi-touch... but I don't imagine they'll introduce simultaneous button-presses to the iPhone interface anytime soon.

I imagine that as multi-touch devices become more prevalent, the idea that the computer won't register multiple touches at all times will eventually seem old-fashioned, since it's based on having one cursor, rather than ten.

Are there any multi-touch features of the iPhone other than pinching?

To enable CAPS LOCK go to settings/ general/ keyboard, and turn on Caps function. Now when you double click the up arrow on the keyboard you caps it.

Multitoch can be tested by viewing a webpage or picture and doing the two finger pinch or stretch.

The only other multi-touch function of which I am aware is the 2-finger zoom-out in Maps

to clarify Hearkat: if you go into Maps and tap the screen with two fingers at once, you will zoom out. Tapping it with one finger twice (double-tapping) zooms in. I like these gestures as an alternate to pinching, since Maps seems very touchy about "margins" -- that is, if you pinch out over the "menu bars" you're likely to jump the map to a different location.
