Jailbreaking

First of all hi, I'm a new member. I have a ps3 which was running 4.82 Cobra CFX. It had a system error so I had to download OFW 4.83. Now my PS3 works, thankfully. But now,
A-) I have to wait and jailbreak it again
B-) Just upload CFW 4.83 without jailbreaking?

I don't know much so.. Any help will be appreciated. Thank you.
