Can I jailbreak a brand new iPhone 6 plus?

I think it's running iOS 8.

Upgrade the iOS to 8.1 and then use Pangu software to jailbreak.This should be done soon if you wish to jailbreak as the exploit used to jailbreak will be fixed in the soon to be coming 8.1.1 update.The jailbreak will be an untethered jailbreak.

It will be iOS 8 since that's what it launched with on Friday & no you can't since there is no jailbreak available.

Right now there is no jailbreak available. I wouldn't jailbreak it just in case anything happens to it if one does come out. Remember, you are ditching your apple care if you jailbreak. So if you mess up your iPhone, you can't do anything about it. You must deal with it yourself.

No, you will have to wait till someone makes an ios 8 jail breaker, I am waiting for pangu to do so

They are working on it so you can check whenever you want on this website pangu.io
