==================================================
Lets be clear before you even read any further.
This is ONLY for people who have accidentally upgraded to v1.1.2 from previous firmwares and are looking to SIM UNLOCK their iPhones again.
THIS IS NOT FOR THOSE WITH IPHONES WITH V1.1.2 OUT OF THE BOX AND WISH TO UNLOCK!
==================================================
Right, now that is over lol let's get down to business. This is a very easy way to fix your "Bricked" v1.1.2 iPhone that you accidentally upgraded.
The following instructions should only be followed if you are confident enough with Downgrading, Jailbreaking etc
Downgrade the main firmware from v1.1.2 to v1.1.1:
Connect the phone to the computer and launch iTunes.
To enter recovery mode, connect the phone to the computer and press and hold the Power button (on top) and the Home button (on bottom front) simultaneously. After about 15 seconds phone will appear to turn off, release the Power button but keep holding the Home button. After about 15 seconds the computer and iTunes will detect the phone in recovery mode, and you can perform a restore. IMPORTANT: If you just click the restore button, it will restore it with the latest firmware. It's much safer to manually select firmware instead. If you want to manually select a different firmware you can hold down SHIFT key (Windows) or Option/ALT-key (Mac) when clicking the Restore button, and it will let you choose firmware file. Download the wanted firmware at the bottom of this guide (http://iphone.unlock.no/#restore-firmware-files) (you would normally want 1.1.1).
You will get an error when restore is complete, just ignore it and run AppTapInstaller.exe (http://www.nullriver.com/%7Eadam/AppTappInstaller.exe) (to Mac users: Just open iNdependence and leave it for a minute and it will coax the phone back into normal boot - you can skip step 4 Mac Users!).
AppTapInstaller.exe will fail, but your phone will get to the Activation Screen now!
When on the activation screen, just follow my tutorial to jailbreak and bypass activation (http://iphone.unlock.no/#Bypass-Activation-and-Jailbreak)Now your phone main firmware is ok, but you should also downgrade your baseband firmware.
Easy Jailbreak /Activation for v1.1.1
Make sure you have a SIM-card with PIN turned off, and power on your phone (the supplied AT&T card works fine).
On the activation screen, slide to emergency and dial: *#301# to make the phone call itself. (If the incoming call dialog quickly disappears but it keeps ringing, just dial 0 (remove *#301# first), and it will call itself)
Answer the call, and tap on Hold
Phone will call it self again, tap Decline. You will now be returned to the normal dialer.
Tap on contacts, and tap the + icon to add a new. The only info you are going to add to this contact are two URL's. To add a URL, tap Add new URL. The first URL is prefs followed by a colon: prefs: and the second is jailbreakme.com. Tap Save.
Your contact now has two "web pages" - tap on the first one (prefs:). This will take you to the settings dialog. The reason you want this, is because you need to connect to a Wi-Fi network, so tap on Wi-Fi, and get connected to a network, and make sure the icon on top of the screen is indicating that you are connected. While you are in the settings dialog, you should also set: General → Auto-Lock → Never.
Now, press the home button, and again, slide to emergency dial 0, Answer the call, Hold and Decline the new call so that you get to the contacts. Tap on your contact (No Name), and this time tap on the other home page, jailbreakme.com
Safari will launch and show you a webpage. Read through the text, before you Install AppSnapp
Phone will return to activation screen, but don't panic, just wait.
Phone should automaticly restart after almost a minute. . If it does not restart withing 2 minutes, click here (http://iphone.unlock.no/#exploit-fails).
When the phone starts again, it should no longer say Slide to emergency, but rather Slide to unlock It means it was successfull! Activation is now bypassed, and phone prepared for software installation! (If you are going to use an AT&T SIM, you won't need to do the next step.)
Downgrading the Baseband Guide
Make sure Modem version is 04.02.13_G in Settings → General → About.
Set Settings → General → Auto Lock → Never
Start Installer and install BSD SubSystem found in System Category.
Go to Sources and tap edit and add http://i.unlock.no/
Now install "BB Downgrader (1.1.2)" found in Unlocking Tools category. This will take around 5 minutes.
When done, restore your phone (http://iphone.unlock.no/#recovery-restore-mode) to get 1.1.1 firmware reinstalled.
When phone have been restored, you can Activate and unlock as normal (http://iphone.unlock.no/#Bypass-Activation-and-Jailbreak).
