    Default [Firmware] Layout Guide

    Hey All,

    I am looking for a good guide to how iPhone is set up, with regards to flash memory, geared towards a more technical audience. I'm a newbie to the iPhone world (just bought a 3G), but am also an embedded systems developer.

    My plan is to perform an jailbreak using some of the recent tools, but before I do that I would like to understand what's going under the hood more. Most of the info I find on-line is more of the how-to style of hacking info, with no theory.

    I guess I would like to see things like:

    * a map of flash memory, laying out bootloader(s), baseband, kernel, filesystem (or whatever makes sense in the context)

    * details on what does and does not get changed when Apple puts out an update.

    * which sections are modified by jailbreaking

    * how does the jailbreaking work

    * what happens when itunes does a "backup" and "restore"

    * what kinds of filesystems are used

    * what part of the system runs DFU mode. (the bootloader?)

    * et cetera

    Can anyone point me a good wiki or two?

    Thanks!!

    Anyone? I have been poking around dev team code a bit, but haven't found much on this level.

    My questions seem (to me) so basic to hacking any device. What I am I missing?
