First im from Manhattan NYC USA.
I have just Recieved my new 8gb iphone with firmware 1.1.2 bootloader 4.0.6 and baseband 04.02.13_g.
I have tried every trick in the book. Downgraded to 1.0.2 tried to revirginize, erase, ieraser, ieraser 2 ,virginator.sh no matter what i do i keep getting back to the 04.02.13_G baseband and bootloader always comes back to 4.0.6.
Apple improved there security by changing the rewrite permissions for the secpacks(I believe.) rewrite flash and erase commands are useless.(not totaly useless they can erase your emi ect,)
This is what i was able to do and very simple to do.
I downgraded to firmware virsion 1.1.1 applied the *#307# methood and jailbroke it with jailbreakme.com. installed bsd open ssh and oktoprep.
And updated(not restored) to 1.1.2 via itunes.Used idemocracy 2.0 and
I had a jailbroken iphone with ssh wireless. no sim card activation tho

(
so basically i have a 8gb ipod touch. If you use anysim1.2 on my version iphone i can confirm that it will hang on flashing the firmware. then if you do a hard reset it will hang on boot.
Next step restore 1.1.1 in dfu mode with itunes,
This is done all on my pc

I am also applecertified bench technician but am not a dev. (Developer/Programer).Hope this is helpful.
There's always a contribution and cause the iphone dev team and otheres are the cause , i contribute by shareing my experiences.
If ome one has a fix for my oob 1.1.2 iphone .Pls feel free to share.
Thanks CityRich.
