Guide: Virginize Baseband 04.01.13 G
From HowardForums Wiki
You dont need a computer for this method but you will need the installer.app isntalled connected to WiFi recommended not Edge.
Did you unlock your phone with old firmware and want to update to v1.1.1?! Your phone needs to be repaired first! GeeZuZz has set up the "world's first" fully automatic "virginizer" (using Elite Team's loader and Dev Team's exectuable) that will fix the phone for you in less than 5 minutes!
If you have an unlocked 1.0.2 iPhone, or upgraded to 1.1.1 and have "damaged" imei (0049) you need to repair your phone. I have now put together the ultimate repair solution - this is the absolutely easiest way to repair the phones (virginize). To do so, just add http://i.unlock.no/ as a Source in Installer, make sure BSD Subsystem is installed (else it's in the System category) and install The Virginizer found in the Unlocking Tools category. There's two versions, use the one corresponding to your Modem firmware. And remember, you got it here first!
IMPORTANT Do not use this script if your baseband firmware is 04.02.13_G (main firmware version does not matter) - check this in Settings - General - About.

How to "Virginize" your phone:
Ignore all long and complex tutorials - GeeZuZz has setup a fully automatic script that will repair the phone so that you can upgrade it.
You would want to do this if you upgraded to 1.1.1, and now have 0049xxx IMEI, and Modem version 04.01.13_G. Check this in Settings → General → About.
1. Set Settings → General → Auto Lock → Never 2. Install BSD SubSystem found in System Category. 3. Go to Sources and tap edit and add http://i.unlock.no/ (if you haven't already). 4. Now install "Virginize 04.x" found in Unlocking Tools category. This will take almost 10 minutes. 5. When done, restore your phone to get 1.1.1 firmware reinstalled. 6. When phone have been restored, you can Activate and unlock as normal.
Only use if you never updated to 1.1.1 before! (that means, only use if your Modem firmware is 04.01.13_G. Check this in Settings → General → About).
If the script completed without any errors, it's 99% sure it's working.
