I noticed I had to click the home button several times today to get the phone to react My Mom reported the same today. I have the 32G and she has the 16G iPhone 5. Could that be software related? Or just hardware? I also noticed my Home button seems more clicky or noisy. It's not the softer sound of my 4. Perhaps I am not picking and maybe I shouldn't expect the same feel of the Home button as my 4, but it doesn't feel as solid as I would expect.
