There is a splitter fitted to the cable to get the 360 and hub connected, so if you return the 360 it's best for a tech to replace the splitter with a connector.
As for broadband: VM's not the cheapest for broadband-only customers and I always recommend looking for alternatives (unless you want a Stream box).
