Inside the iPhone 4--courtesy of Steve Jobs

The iPhone 4 got a preemptive teardown on Monday courtesy of CEO Steve Jobs at Apple's Worldwide Developers Conference.

Though a pre-commercial version of the iPhone 4 was notoriously taken apart by Gizmodo--and no doubt other meticulous teardowns will follow--there's nothing like an official peek inside by Jobs to set the record straight.

So, what's going on inside? Not surprisingly, one of the key goals is to pack more features and functionality into a smaller space: at 9.3mm thick, the device will be 24 percent thinner than its predecessor. And to make this point, an Apple video released Monday shows an animation of the Apple A4 chip package shrinking to accommodate a wider battery. This wide-and-thin battery motif can be seen across a number of larger Apple products, including the MacBook Air and the iPad.
