I have an Iphone 4g on iOS 4.1

I am from New Zealand so apparently its already unlocked when you buy it from the New Zealander IPHONE sales ( vodafone NZ ) i wanna jailbreak it using Greenpois0n but im worried that it will elimnate the unlock that apple has put on it for it to be used in New zealand, can anyone help me with this ? also is it reversable if i want to get warranty on it

Jailbreaking does not remove official unlock.

And yeah you can remove jailbreak by just restoring/updating the phone.
