Understanding function of baseband

[chenchend]

I recently got myself an iPhone 4 with iOS 4.2.1, modem firmware/baseband 3.10.01. but i do not have any commitment with any sort of telco carrier. do i still need to unlock the baseband? or can i just jailbreak it with to-date greenpoison? still new with the iphone thing. thnx~

Is the phone lock to a carrier? If yes and you want to use it on another carrier, the phone needs to be unlock. And, 3.10 baseband can only be factory unlock. Ultrasnow software unlock does not work on it.

And, Greenpoison is to JB the phone. Unlock and JB are two different things.

If it's not an AT&T iPhone, I think you can bring it to a carrier that supports the iPhone to have it unlocked (some may charge you a fee) or it may already be unlocked.

If you have an unlocked phone, you do not have to be concerned about upgrading the the baseband when you upgrade the firmware (iOS).

Yes you can just jailbreak the phone.
