Here are two simple but useful tips from TUAW readers David B Alford and Andrew Akker that help you navigate through your iPhone or iPod home screens. David points out that if you tap just to the left or to the right of the dots at the bottom of your screen, you can move a page at a time without having to drag. Tap left, you move left. Tap right, you move right. It's quick and it's easy.
Andrew figured out how to pause his drag Home screen drags. If you start to move between screens by dragging and then tap the dots control during that drag, screen pauses. You'll see bits of both home screens at once, and can interact with them normally by tapping icons. You can see up to 24 icons at once (16 off to one side, 4 along the other side, and 4 in the bar at the bottom).
I've tested both tips extensively and they work great -- two really nice additions to one's Home-screens skills.
