Firmware of an iPhone Prototype discussed on Mac Rumors.

Based on /private/var/db/dyld/update-prebinding-paths.txt this release is called Alpine Build 1A420. The main user interface of this firmware is SkankPhone.app which features a built-in Operator screen, used to test the various buttons and sensors. Interestingly, this version of Operator plays portions from INXS songs when testing the speakers, whilst newer versions play various Chinese songs.

Restore

Instead of it being done through a ramdisk, the restore tools seem all to be right there in the OS. This is probably because they originally did restores through userland.

Baseband

  • The iPhone Prototype came with 03.06.01_G[1]
  • The firmware dump comes (in /usr/local/standalone/firmware/) with 03.06.00

Flashing 03.06.00 on a retail iPhone can be done with bbupdater, but results in a loss of Carrier Network connectivity.

Kernel Caches

In /System/Library/Caches/com.apple.kernelcaches, there are kernels for other CPUs, such as S5I3000, S5L8900XFPGA and Freescale MX31. This is probably because Apple did not know which one to use at the time, and/or they had different prototypes with different CPUs in them.
