Who better to field questions about the iPhone than the guy from Apple's own guided tour video, right? Pioneer Press' Julio Ojeda-Zapata had a chance to chat with him on a couple occasions (turns out he's Bob Borchers, Apple's senior director of worldwide product marketing for the iPhone) and he was able to squeeze answers to a couple pressing matters out of him -- things like "WTF is with the recessed headphone jack?" and "can the iPhone be upgrade to 3G, please?" The answers are all pretty predictable ("we had to" and "it's a hardware issue" for these two, respectively) but it's a good read nonetheless. We especially like the bit promising "a lot of improved functionality that will be rolled out on a regular basis."
