Upgrading 3.9FB bootloader to 4.6 - reversing iliberty+

[firestarter03]

Since that you can now use O2 PAYG sims on a stock iphone, I would like to upgrade my bootloader back to the stock 4.6 before restoring my iphone. I have been searching and found there are 2 possibilities:

1. Use bootneuter
2. Use iliberty+ again and select Upgrade bootloader from 3.9FB to 4.6 (stock)

Which should I do? Am I correct in understanding that my baseband was untouched when I used iliberty+? It is 04.04.05_G at the moment.

I just want it in stock condition before I update to 2.0.

Thanks in advance.

Nevermind, sorted it myself using iliberty+ by jailbreaking again and selecting to upgrade the bootloader. 2.0 is working great for me

I could write a guide of what I did if anyone wants me to...
