Over a decade ago I was a moderator on the FlashKit forums[1], and this page turning effect was all over the place.

As for touch related, I think they both have iOS / mobile web apps as do others.
They have all been around since before iBooks.
The first time I saw a finger following page turn on iOS was pre iPad via Pixelmags. I am not sure when it make it to market though, but I'm sure it was before the iPad launched.
