Voice Control can be activated in two ways:
From the remote: When you're using the Apple Earphones with Remote and Mic that come with the iPhone 3GS, simply hold down the center of the remote (not the plus or minus buttons, but in between them) for a few seconds and Voice Control will appear on the screen.
From the home button: Hold down the iPhone 3GS' home button (the button centered just below the screen on the face of the phone) for a few seconds and Voice Control will appear.
