The home button is going away
Recently, there have been rumors about the next iPhone not having a home button. Gruber thinks that the home button isn’t going anywhere, as does Benjamin Brooks. I disagree. iPhone 5 will look like this:

And you might be saying, “But how will you get to the home screen if there’s no home button?” “How will you take a screenshot?” “What if I need to reset my iPhone?” “Gestures are not discoverable!” etc. etc. etc.
See, the home button is there and not there at the same time. That bottom area where the home button used to be will now become a gesture area, sort of like the Magic Trackpad. You’ll still be able to press the bottom area of the iPhone, hear an audible “click,” and get to your homescreen. But with a gesture area, it opens up a world of possibilities. Imagine swiping up with two fingers to access the multitasking tray instead of double clicking the home button. Swipe left and right to switch apps. Tap with two fingers to pause and play music. Nice, no? And since the gesture area functions just like a home button if you want it to be, all those complaints that people have been lodging are taken care of.
