afaik
Sky have not sent any updates
I would imagine there is one on its way to help sort the UPnP problem, which some people may or not have.
I would also imagine that the Netgear router that is used at the moment will be replaced for a better more robust (and works better) in the not to distant future.
Sky have not decided to give free / cheap broadband for them to look good, they have done it to make money. If your router (if not the Sky one) is not capable of what Sky have planned for the future, you are stopping them from making more money from anything you may buy on demand.
There are a lot of exciting things happening and you will soon see, that Sky BB is the one that everyone wants. All they need to do is sort their customer care / communication out and they are over half way there.
