So I've had Orange BB and phone now for 6 weeks or so, which means that the DLM should have settled down now.

Its settled at around 11mb down and 1mb up which is way faster than I got on Sky LLU. Best of all, Orange didn't charge me for the "new line" and the Quidco cashback offer tracked at £150. Including the 3 months free offer, it means that I am paying £3.65 a month for line rental, off peak calls and unlimited BB for the next 18 months! Quite a result so obviously I'm a very happy. As an added bonus Orange sent me 2 routers by accident, so I put one on ebay and got £20 for it .
