I don't wanna quote Jobs but really "You're doing it wrong". I never have trouble pulling down the Notification drawer. I know the problem you have, I used to have it too. The way I fixed it was to simply PULL DOWN. One swipe down. Going down to >70% of the screen would guarantee it opens but its needless. I simply do ONE single SHORT pull downwards. I apologize if this wasn't the issue you were talking about. Android has A LOT of problems, but the Not. Drawer isn't one of them.
