Well, it doesn't for *any* app that I've written that uses the new automatic save-and-restore - and I've written half a dozen, as test cases. They all work, in the sense that I can test in the normal way: e.g., run from Xcode, click the Home button (on the device or Simulator), stop in Xcode, and run from Xcode again - presto, we launch with restore (proven by how it looks, by logging, etc.).
But if we put the application on a device, launch it from the device, click Home, restart the device, and then launch from the device again, there is no state restoration: we are doing a cold start.
Do you actually *experience* the contrary? If so, is there some piece of the puzzle needed here in my code that would make the difference between save-and-restore working *most* of the time and save-and-restore working even after the device is restarted?
