We don't know yet. It probably won't. There's a lot of concern right now because there's still quite a few people, myself included, waiting on iPhones to get to them so we can unlock them...but Apple may release the next firmware update before we get them, and in which case we're all screwed.
Our only hope is if we can somehow choose which firmware we want on the phone, which I don't think we can, or, if the hackers can come up with a quick solution to this upcoming firmware update once it's released.
