I am new to iPad and am learning all the time. I have read articles that say that version 4.3 is supposed to close a program with a five finger pinching motion and that you can change from app to app by sweeping a 5 finger motion. My new iPad 4.3.4 will not do this and that would be so much faster than looking for the button in the dark, haha. Can anyone help? I heard that 4.3.5 is out.
