A couple iPhone Scrolling Hints

What I discovered is that if you first double-tap on a column (like those found on many news pages or standard web pages), the screen will zoom in to fit the whole column (that part, most people probably already know). From that point, though, you can double-tap in the lower ¼ of the screen to scroll down a nice amount for reading. Double-tapping in the upper ¼ of the screen will scroll up.
