Hello, I noticed in my new Iphone 4s that the home button is not 100% fixed. What I mean is that you can noticable (15-20 degrees) turn it left/right when you press it with your finger and turn a bit. It's visible because then the square painted on the button is not in line with the screen, edges of the phone. Has anybody noticed that? It's nothing really that affects the phone's functionality, but it spoils the looks when you can see that the button is not 'straight' and i have to align it from time to time by turning it with my finger back into the correct position.. I attach a photo to show you the problem.
