Apple on Friday officially brought its iPhone to China Mobile's 763 million subscribers. But don't go thinking that good news for Apple had CEO Tim Cook giddy enough to let slip any details of the company's plans.
During an event launching the iPhone on China Mobile, Cook was asked whether Apple might launch an iPhone with a bigger screen or offer flexible displays in future models. All Cook would say, in essence, is that customers can expect some nice updates in the future.
