Software unlock (such as ultrasn0w) may or may not be broken by firmware upgrades, you should always be careful.

I see, I think my phone has a factory unlock then.

Yeah, that would explain the fact that you were still unlocked after upgrading, makes sense...

I'm liking the cydia app, that is a pretty good peace of Kit. Nice, very nice.

So, how is a Factory unlock done on the iphone.

Well they're sold already unlocked, take a look at Unlock - The iPhone Wiki for technical info.
