Hi everyone. I've noticed recently that my 32gb iPhone4 I can open the facebook app once, to check things like notifications, of which I have to look because they don't get pushed into the notification center. But if I hear, Facebook, two new items, I click it and it takes a few minutes, then it does the sound like the app is closed, and that's it. I don't know if this happens on anyone else's devices. And if I click the app switcher, it's sitting in there.
