App no longer compatible with anything other than iOS 6 (aka newer iPhone/iPad)

Since the latest update - optimized for iPhone 5/iOS 6, the app hasnt worked on my iPod Touch. If you cant write an app that is backwards compatible, at least indicate to us that we can no longer use this app on our older platforms! Ill be deleting the app and not bothering with it anymore... Too bad, as it was a good app.
