I find that I “flick” my iPhone screen — dragging the UI of certain apps to the bottom just to let them pop up again — just for something to do. For example, when I’m waiting for Mobile Safari to load a page or Twitterrific to load some tweets, I’ll flick the page.
Tweetie is the only app I know that makes use of it. More should, as I’m sure I’m not the only one who does this.
Gowalla does it now too when you need to do a refresh on spots. It is such a natural movement.
Exactly.
