Fascinating. Could this method be used to boot iPhone OS 1.0 (or at least 1.1.1) on an iPhone 2G with 16GB NAND maybe?

The oldest iPhone OS that natively boots on my particular one is 1.1.4, 1.1.1 (which is the highest version number where you can trivially escape the OOBE via the emergency dialer) fails to initialise the FTL (flash translation layer), probably because the chip is sufficiently different from that used in the older phones.

It would bring me great joy to be able to relive emergency dialer hacktivation again, but I have lost that particular iPhone 2G, and only have this 16GB one left.
