You will be able to JB on any of the following fimrware versions:
6.0 6.0.1 6.0.2 and 6.1
Best bet would be to restore with itunes to the latest 6.1 firmware and then JB it.
I updated to 6.1 OTA I'm not really concerned. It's more of a precaution to restore than a must.
I can always restore as new if I need to.
