Unlock help! iPhone 2g on 3.1.3

[TheMaD.ScienTisT]

I have an iPhone 2g that I had just updated to 3.1.3 and used the Spirit jb program to jailbreak. However, I do not have the SIM it came with so I installed Ultrasnow but when I put my (non-iphone) SIM in I get the "Different SIM detected" screen. I was about to try Sherif Hasim’s activation method but it appears Apple fixed the bug in their servers in late october... I'm not quite sure what to do. Should I restore and try with another program such as redsnow or pwnage tool? Any help will be much apreciated

Cheers

Restore and use redsn0w. Also ultrasn0w is not needed for iphone 2g. Bootneuter is what unlocked them.
