So I got my first rejection from the App Store today.

Say what? Now, I'm the first to admit that my icon is a bit simple. But it seems like a reach for Polaroid to be able to claim that all black squares on white rectangles are infringing on their rights. And Apple did suggest that you use distinctive colors and a strong outline to promote user recognition. Here are some other screenshots from the app:
