This will not work on your phone if it came with 1.1.2. Ive been looking for a this this for a few weeks. I found it today and it worked like a charm...

If you have a phone running on 1.0.2 and baseband 04.01.13_G
just donwload these file and run these commands...

Step 7. Connect to your iPhone using Fugu. Type the iPhone’s IP address. Enter “root” as username, “dottie” as the password (Find it from settings > Wi-Fi, choose the connected Wi-Fi’s blue arrow.) Download the pack here. (If you got stuck in “waiting for data”, you can try to download this pack.) Extract the package by right-clicking it and use BOM Archive Utility. Upload it to iPhone’s “/usr/bin”.

Step 8. Open Terminal of Mac OS X. Type “ssh root@192.168.0.1″ (change 192.168.0.1 to your iPhone’s IP address). Type the following commands consequently. Make sure you press Enter key to execute it for each line:

launchctl remove com.apple.CommCenter

cd /usr/bin/

chmod +x bbupdater

bbupdater -v

chmod +x ieraser

ieraser

bbupdater -v

bbupdater -e ICE03.14.08_G.eep -f ICE03.14.08_G.fls

bbupdater -v

Step 9. Make sure you see the 03.14.08_G baseband in the end of step 8. Shut down the iPhone now. Open it again. Connect to your iPhone again using Fugu. Remove the files we uploaded in step 7. Download the virgin pack here. Extract the package by right-clicking it and use BOM Archive Utility. Upload it to your iPhone’s “/usr/bin” by Fugu.

Step 10. Open Terminal. Type “ssh root@192.168.0.1″ (change 192.168.0.1 to your iPhone’s IP address). Type the following commands consequently. Make sure you press Enter key to execute it for each line:

launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist

cd /usr/bin

chmod +x ./norz

./norz seczone.backup 0×3FA000 0×2000

chmod +x ./iUnlock

./iUnlock ./ICE03.14.08_G.fls ./eliteloader.bin

chmod +x ./bbupdater

./bbupdater -v

./bbupdater -f *.fls -e *.eep

./bbupdater -v

launchctl load -w /System/Library/LaunchDaemons/com.apple.CommCenter.plist

Step 11. Shut down the iPhone, open it on again. If you got the incorrect IMEI, please remove your SIM card and try to run Step 8-10 again. Check also from Settings > General > About. You should see 1.0.2 and 03.14.08_G. If not, please try Step 8 - 10 again.

What I want to know is WHY would you want to downgrade the baseband itself when you can actually just downgrade the firmware and keep the baseband, use anySIM 1.2.1.u to unlock, install Oktaprep and upgrade to 1.1.2 and jailbreak.

End result is 1.1.2 Unlocked.
