I was telling a friend today that Dr. Kaku is like Mr. Wizard for adults. The way he explains things to the layman is awesome. The guy is definitely a natural teacher.
that's because you didn't do anything when you re-run it, all the code was already there, so the script just quit. If you are Jailbreak with no issue you don;t need to bother with these updates. Limera1n is like a screwdriver that you use to screw something in, if you got your screw in, you don't need a new screwdriver... however if you were unable to screw it in, them try using the newer screwdrivers
no need to unless you got issues, in that case, restore and run the most recent version, if you are running fine, themyou don't need to re jb, limera1n is a use once and forget about type of app
