The article was a bit misguided to me. It's not about making the status bar black and rounding the corners. That isn't going to magically solve the problem the author tries to explain but doesn't really come through -- which is that if you have a pane in your app that scrolls but leave other elements of the app fixed to the screen, the UX "feels" restricting, whereas if you scroll the entire app, the content seems like it's unbounded. That I get. Now, whether you make the corners rounded or not, that's just an extra design detail. But the way to achieve unbounded content is to just make your app full screen. Drop the fixed navigation along the bottom, put it in a hidden sidebar. Now this is great, but it's not a magic bullet. What the article didn't say is, there are usability concerns with this too -- if you don't have a lot of navigation, having to show the sidebar is just going to be an extra step for the user. Of course, if you can keep your entire app in one screen without the user needing to scroll anything, that's ideal.
