No date when the cab will be ready, samknows goes more on the exchange live date- though that can be wrong.
FTTC generally goes live with the first 10 cabinets, then more will follow on, the BT asdl wholesale checker is usually the most accurate way of knowing.
If you can find your cabinet and keep any eye on the roadworks- roadworks.org if it covers your area will say for any work happening.
Can possibly try some isp's but they will either give a rough date or say its not available yet.
