From the now we've heard everything department, an analyst is "predicting" that the 4th generation iPhone's plastic casing will be multitouch enabled, just like Apple's new Magic Mouse.

Not "predicted" of course is how it would work, and how it would filter out things like holding the iPhone for normal use vs. deliberately initiating a multitouch gesture on the back of the case.

Again, with Apple anything is possible, but is this desirable? Can you see Apple doing it?

The Palm Pre and Pixi have a multitouch area below the screen to enable consistent gestures for "back" and to bring up the app launcher. Is that preferable?
