If my iPhone 4 is dormant and I want to turn on the screen, I normally click the home button. However, sometimes - like today - I can press it and absolutely nothing happens. I have to press the on button (the one I normally would use to turn the phone off) to see my home icons. Weird. And once I've opened several apps and want to close them, I would double-click the home button and select which apps to close. But now I double-click and nothing happens. I do have the softkey button activated on the phone, so I can just tap it and go back to my home screen, but it doesn't allow me to see what apps are currently open, so I can't close any out. I have to turn the phone off, then back on again, to do that. What a hassle. Is there something I've done to cause this or a better workaround?
