sim card

jakes

I asked before with no answer, i broke my 1st iphone 4s and got a new one, they gave me a sim card out of the phone. now I am thinking of jb my phone and would like to know if I should put it in or not before i proceed with a jb?? What would be the pros and cons of putting it in???
I hope I can get an answer this time.
Thank you in advance.
