Screenshot on the iPhone/iPod touch

If you own an iPhone (or iPod touch) and you want to show interesting programs or hints/tips to others, you can easily make a screenshot of the currently showing screen by simultaneously pressing the Home button and the sleep/wake key. The screen will shortly fade out to white, fade in again and you will hear a clicking sound.

The actual pictures can be found in a photo album (called "Saved Pictures" or similar).

By the way, I use iPhone Explorer exchange files between my iPod touch and the PC, for example the screenshots I took.
