How many Multi-Touch points can an iPhone/iPod touch/iPad have at the same time?

    I am curious as IIRC (but forgot where the article is on the Internet),
    if a touch surface is wanted to be able to detect more than 1 touch point at the same time,
    then that touch surface needs adding 1 more conductive(?) layer.
    (e.g. 2 points -> 2 layers, and so on)

    So I wonder how many these layers are on the iPhone / iPod touch / iPad or even the trackpad on every MacBook (Pro).

    (correct me if I'm wrong)

    Just curious, thanks in advance! :)
