white iPhone -- spotted only in the hands of Woz and occasionally in those of our own Richard Lai -- may ship after all. After hearing from Apple that it was being delayed twice in 2010, we've heard an extended radio silence ever since. Sure, we've seen hints here and there from third parties that this here unicorn was still making its way through the production line, but there's nothing quite like a direct tweet from Cupertino's senior vice president of worldwide product marketing to really rekindle some interest. In response to a question on how to obtain a white iPhone, Philip Schiller fired back: "The white iPhone will be available this spring (and it is a beauty!)." That's about as clear-cut as it gets for now, but we've still got a few inquiries we'd love answered. Is he talking about the iPhone 4, or the next one in the pipeline? And does he have any intention of building us up, only to let us down (let us down) once more? We shall see, won't we?
