if you got 1.1.3:

update - here's what you want to know:

Its not jailbroken. You WILL lose all your 3rd party apps if you upgrade.
Its not unlocked. With any method. If you're not using your iPhone with AT&T, and you upgrade right now, you will not have a working phone, and may not be able to fix that for a while.
If you've already upgraded to 1.1.3, downgrading to 1.1.2 does NOT work. Supposedly, downgrading to 1.0.2 works, so if you still want a jailbroken iPhone, you'll have to go down to 1.0.2, and follow the usual guides to upgrade to 1.1.2 and jailbreak etc.
