Talking Firmware 1.1.1 downgrade
It seems the folks of at hackentosh have been able to get a firmware downgrade. The process is still being worked on & is very shaky. But headway is taking place. And bricked phones are comming back to life.

The process is being named Kmac after the user who stumbled across.

Here is the thread so you all can follow:

Here are the steps:

1) Make sure you have a copy of the 1.0.2 firmware handy and decrypted
2) Reboot iPhone holding top (power) and home buttons *BUT* release the top button 10 seconds into it (right after the screen goes dark)
3) The iPhone screen will appear to be off, but start iTunes (latest version worked for me on the Mac)
4) Option+Click restore and select the 1.0.2 firmware ipsw
5) The phone will restart and error out at the end, this is expected
6) Shutdown iTunes
7) Launch the latest iNDpendence
8) Jailbreak the phone using a decrypted 1.0.2 (it will flash all sorts of error, but stick with it)
9) Activate the phone
10) It will show the SIM error but you should be able to get back in

I installed AppTapp afterwards along with the BSD subsystem and SSH, all working over wireless only. Now we need to see if we can get bbupdate to play ball.

I feel the Kmac solution is allot simpler also this solution began after a call to Apple tech support.

So this does prove there are tools & solutions avil to Apple that us users have not found. Aperently this above method is what the techs in the Apple store have been using to unbrick phones.

Makes you wonder if there is some magic key code one can enter & the iPhone will unlock also.

Guess in time we will know.
