I've noticed a bug with my app on my mother's old 1st gen iPad running iOS 5.1.1. The app supports 4 orientations and opens normally in portrait mode, but when I switch to landscape mode I can only flip the iPad, but can't go back to any portrait orientation. The problem seems to be on iOS 5.1.1 only since my iPad running iOS 7.0.3 doesn't have that issue, just like every iPad simulator Xcode has to offer. I'm using Xcode 5.0.1. I have really no idea what's wrong here.
