HOW CAN I DEACTIVATE GENIUS FROM MY IPHONE, IPAD AND MAC??
In iTunes, click the Store menu and select Turn off Genius. When you sync your iPhone and iPad, genius data should be removed.
At least that's the way it worked when I turned it off over a year ago. I haven't touched it since, so I'm not sure if there are additional steps with iTunes 11 or iOS 6.
