On the iPhone and iPpod Touch when you are entering text in a textarea (a multi-line text input) in a web form, you can't scroll up and down to review the text you have already entered. The two-finger trick doesn't work. This can be a real pain if you are entering more text than can be shown in the textarea.

There is a trick that will allow you to scroll though. Tap inside the text area and hold your finger there to bring up the magnifying glass. Once the magnifying glass is shown, you can scroll by moving it to the top or bottom of the area.
