Just called BT to cancel my old phone line, they didn't want to lose me so done the
160Mb FTTP service for £26 per month instead of £35 p/m, first 3 months free and the usual line rental charge, "unlimited" downloads etc
Result
Just got to wait over a month for the install on 16th Jan and put up with shoddy Edge speeds with a chance of 3G/HSPA until then
