If the parallax effect doesn't work on the iPhone 4, how come I've been reading a number of posts from other forums (as well as my cousins' experience), that iPhone 4 users are getting motion sickness from the parallax effect. And because it's not available in Settings, they have no way of turning it off? Is there a workaround to this? Or are they just seeing things, and getting motion sickness from what they don't see? lol Seriously though.
