Just unlocked my week 40 virgin 1.1.1 with this method, running Fido in Canada. Jon, your guide was great. One suggestion though - Part 3 is useless. Jailbreak is done while activating, so there's no need to jailbreak twice.
Glad that it was helpful! It seems like there have been a couple people that have all been succesful using it. As for the jailbreaking, I was just follwing the guide in the jailbreak help menu there. I never bothered to check it.
