If I restore from backup, will my new iPhone be jailbroken?

My iPhone is jailbroken. I want to back it up, so that when I get a new iPhone I can restore it from iTunes backup. If I restore it from the backup of my old phone, will this cause my new iPhone to be jailbroken?

No. Any type of restore will reset the phone to how you bought it out of the box. Even if you backup the phone while jailbroken & restore from backup. You will lose your jailbreak. From what i've heard, if you now restore your apple products, iTunes automatically updates you to the latest firmware. From my knowledge, iOS6 jailbreak won't be out for another month or so.
