iTunes is not showing me 4.3.3 as an upgrade for my iphone

[Zenitram]

I have a 3GS on 4.0.1 jailbroken. I want to upgrade to 4.3.3 and do jailbreakme 3.0. When I connect to iTunes it says to upgrade, but it gives me a lesser version than 4.3.3. (It's 4.2.1 or something).

Do I need to upgrade, then will itunes suggest 4.3.3 and upgrade again?

Can I somehow force iTunes to upgrade to 4.3.3? Thanks!

Are you using the latest version of iTunes? If yes, iTunes showing 4.2.1 as the upgrade is interesting ... because that (4.2.1) is the latest 3G (not 3GS) version.

Yes, I am updated in iTunes, which is what made me so confused. I'd imagine that if I upgraded iTunes would then show me 4.3.3, but I'm not 100%. I wonder if there's a way to refresh that. If I upgrade it as it is, and it shows me my software is up to date, I can't take advantage of JBme 3.0, which would be frustrating, but I feel this is the best time to try and get to 4.3.3.

Thanks, I thought I was on the latest version of iTunes, but I wasn't. The update now shows 4.3.3.
