iPod touch 101: Access playback controls during lock

Here's a nifty iPod touch-only feature that isn't yet implemented on the iPhone. When your touch is locked, double-tap the home button. iPod playback controls instantly appear. You can do the same thing from your home screen and get the bonus of a "Music" button that takes you instantly into the iPod application. Give it a try. I'd have taken a screenshot but Apple hasn't let us into the touch yet to install custom software like that. The best part? It looks like this feature will be coming to an iPhone near you soon(ish?).
