My iPhone 4 is unlocked, does it mean it is jailbroken?

[sonill]

I have a iphone 4 and it is unlocked. I have bought it from "three" of Australia. It is unlocked because i am using "sim card" of another operator in another country. How do I know if it jailbroken or not?

Are all unlocked iPhone 4 jailbroken or not?

It doesn't mean it's jailbroken. Especially since you are from the land "down under".

Did you purchase it officially factory unlocked?
That means it will accept any carriers GSM sim and it will not lock to any carrier.
Do you see the Cydia icon or any other non-stock icons or items installed?
What firmware version are you on and what's your modem firmware version?

Ok then its Factory unlocked.
That baseband cannot be unlocked thru a JB at the moment so if you're using it with various Sim cards and it works as a phone then its official.
