    Title says it all: do I actually need to put the iPhone into DFU mode before upgrading from jailbroken 2.1 to a jailbroken 2.2 firmware, or can I just option-click restore in iTunes?

    And on a related note, restoring from backup only restores audio, video, apps, and data, not firmware, right?

    No, can upgrade like normal if you are already jailbroken.

    Yes.

    Thanks muchly, between upgrading to 2.1 and the 2.2 release, I bought a Unibody MBP, and I was a little wary of putting the phone in DFU mode, even with the 10.5.5 kexts.
