* NAND和NOR的选取：这个话题争论很久了，iPhone至少表明了Apple的立场，那就是两者都有。NAND闪存中存储了Mac操作系统的大部分系统代码，以及音乐、视频和其他一些非易失性的数据，系统启动代码存储于NOR闪存中。实际上iPhone中有两块独立的NOR闪存，分别位于数字和射频板上，分别对应ARM应用处理器和Infineon基带处理器。
* 说到ARM处理器，它在iPhone中的地位很令人吃惊。我们来算算它的数量：单独有两颗，802.11收发器可能会包含，Infineon基带处理器可能会包含，蓝牙收发器中也可能会有。
* 谈到一个系统里的多颗处理器，iPhone在这点上和PC很不同。iPhone中的多个CPU核分担总的任务，起到不同的作用，在没有任务时系统可以有选择的降频或者掉电来节约功耗。这种系统结构与Intel之前基于ARM的XScale很不同，iPhone本质上是软件驱动的设计。

附英文原文：
I admit it: I'm a bit of a wimp when it comes to Prying Eyes teardowns. Get me a piece of gear with an easily (or at least somewhat ea
sily) removable top, side (or top, depending on how you orient it) or back panel, and I'll gleefully grab a screwdriver regardless of the widget's cost. Well…within reason, that is, and especially if it's no longer working, anyway. If it's free or free-after-rebate, I'm not worried about breaking it during dissection. An already partially disassembled patient is a bonus, as is cereal on the side. Even a double-digit pricetag isn't too much of a barrier, either to my nerves or to the accountants who approve my expense reports.
But when a Prying Eyes candidate's cost crosses the triple-digit threshold, I take serious pause before pursuing the project. And when the cash register rings up a McKinley (or more), I know where to go—in pursuit of a partnership with someone else who's already tackled the teardown!
That's why I locked arms with Llamma.com for my recent analysis of Microsoft's Xbox 360 Elite. And that's why I joined up with Portelligent for this Prying Eyes project. Portelligent published a bill-of-materials inventory and a cost-estimate report soon after Apple and AT&T began selling the iPhone on the evening of June 29. I'm profoundly grateful to Portelligent for agreeing to join with me on this Prying Eyes adventure. By leveraging their existing work, I'll be able to preserve my iPhone's functionality for future hands-on reports, as Apple and AT&T evolve the device's feature set.
