With all the 1.1.2 Guide on how to get this version to work and UNLOCK this is one of the best! It worked like a charm.. I have previously unlocked 1.1.1.. to make everything worked and no errors, I downgraded to 1.0.2 first, did the downgrading baseband then revirginizing it..
I know I do not have to revirginize it again since its already on lockable stage but just to make sure everything will go smoothly I did it anyways.
After revirginizing, I Upgraded to 1.1.1 jailbreak and activated.. Then Upgraded to 1.1.2, NOW, getting to restore mode on this ver really giving me a hard time.. took so many tries but I got it. So I restored to 1.1.1 AGAIN and got the error 1015.. open up iBrickr and got the reboot to 1.0.2 and got another error 1013, so did the fix got the red and finally the activate screen.. Jailbreak and activate it, installed all the files I will need to upload anysim 1.2.1u, Run it and got the unlock successful..
Restored to 1.1.1 got the error 1015 open up ibrickr and did the boot and fix it.. got the activate screen.. do the jailbreak.............................. oktoprep........... UPGRADED to 1.1.2.......... opened the 112 jailbreak folder clicking windows.bat.. watched it finish doing its thing.. gives me reboot my iphone.. I was concerned at first cause after reboot I got the usb and a disk image again, but after 5 sec it reboot itself and there it goes

Unlock 1.1.2... Thanks Salty!
