No, probably still really far off actually. Let me try to explain it in really simple terms... Alright so say you have a house and all of your locks on your house have been broken into (firmware 3.55) and a bunch of people got in and started hiding out. Well then you get pissed off and put all new locks with better security on your doors (firmware 3.56). While this keeps anyone new from coming in you still have all the people already inside your house and there's nothing you can do to get them out.
....unless of course you burn your house down = YLOD
