There was a time when releasing apps only designed for phones was acceptable. That isn't the case anymore. This episode explains how to create a responsive two pane layout (master/detail) in your app. While there's tons of other ways to support large screens as well this approach is something that works for many apps.

PART 5: BACKWARDS COMPATIBILITY & MODERNISATION
This episode talks about how to make the changes done to the app work on older devices. While I personally believe that we're already in the point that supporting only 4.0+ devices is OK for new there's still many apps that should support 2.3- as well.
