Thanks to Tahoma Toelkes, we now know that the mousewheel event fires
when you do a two-finger vertical dragging motion on the phone. It
seems that this only works over certain elements, like textarea. It
also seems to work only for vertical dragging, not horizontal. Still,
it's a start! I've used this info to scratch my biggest iPhone itch,
which is to be able to drag and drop elements on a page.
Here is a very simple demo. Touch the blue box with your index finger
and middle finger and then drag it up and down in a precise vertical
line. It should move with your fingers. With the vertical
limitation, this still isn't very useful, but it's better than
nothing, right!
