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.
