Sorry, I should have mentioned that this is beta software for developers. If you have a Mac you can get enough of the developer stuff to enable them for about $5.00 but you can't enable them from a PC. See How To Enable Multitasking Gestures In The iPad 2 for more information.
Cool. Thank you. I had heard about the developer mode, but was not sure how it worked. Are there other benefits of switching to developer mode? Well, I guess I could google that.
