Apple’s iPhone boasts a taller screen, as rumored, and that means basically an extra row’s worth of information in terms of the home screen. That’s going to result in some changes in the design language app-makers have to speak, but Apple’s already updated its first-party apps in order to give devs a roadmap. iWork, iMovie, and Garageband, as well as all the stock apps that ship with the iPhone, are now designed to take advantage of the change by providing extra information. For existing third-party apps, there’s a compatibility mode that will letterbox content, displaying black bars on either side. It’s better than just stretching things in terms of providing a pleasant, consistent user experience.
