Steve Jobs was unveiling the iPhone 4 at Apple's worldwide developers conference in San Francisco last June when disaster seemed to strike. Jobs found he couldn't connect to the conference center's Wi-Fi network. Fortunately, his technical team rapidly pinpointed the problem. "We figured out why my demo crashed," Jobs announced to the audience. "Because there are 570 Wi-Fi base stations operating in this room. We can't deal with that."
