I had the same response. If you double click the "home" button, then there isn't the red button immeadiatley. I figured it out, you have to hold down one of the displayed apps on the bottom (as if you were deleting one), then the red button will appear, it looks like a "DO NOT ENTER" sign. Then go home and open up your photos or camera, to access camera roll, that's how you do it. Hope that helps.
