CUPERTINO, CA—Only a month after the much-heralded announcement of the iPhone, Apple CEO Steve Jobs confirmed that his engineers were already working around-the-clock on the touchscreen smartphone's far-superior replacement. "We looked at [the iPhone's] innovative user interface, the paradigm-shifting voicemail, the best-in-class mobile browser, and we realized we could make all that seem ridiculously outdated by the time the product becomes available to customers in June," said Jobs, who described the project as "Apple reinventing the iPhone." "When the second-generation iPhone comes out this fall, we want iPhone users to feel not just jealous, but downright foolish for owning such laughably primitive technology." Jobs also hinted that the second iPhone device would not be compatible with existing Mac computers, third-party peripherals, or any future Apple products.
