So when I got my iPhone (about 3 months ago), I unlocked it OTB using AnySim. I was still on AT&T, I just did not want to extend my contract.

What I am wanting to do is upgrade to a locked version of 1.1.3 (because I understand 1.1.3 has not been unlocked yet).

Should I just use OneSim or Virginize and then restore to 1.1.1? And then upgrade to 1.1.3? Or should I use another method.

I want to be safe as possible and not take any chances on having this thing brick.

Thanks a lot for your help.
