I finally uploaded my app to iTunes Connect today, and it asked me for a 3.5 inch screenshot.
I didn't develop this app with the iPhone 4S in mind, since Apple dropped support for the 4S on the later versions of iOS. This app has no storyboard that lets it run on a 3.5 inch iPhone 4S.
Do I still have to make the app support the 4S (and submit the corresponding screenshot), despite Apple dropping support for the iPhone 4S?
