Just so you are aware there is a new product launched today called "Fibre Advance Support" or what used to be the Option 3 Plus Fibre mythical product
Just ordered it, basically its for people who have a Fibre enabled exchange and FTTC boxes all over the town but can't get the minimum 15Mb required for BT Infinity when they run the line checks.
Just ordered it here, line checks showed Fibre enabled exchange, but not suitable for Infinity due to line speed estimate being 12Mb.
Otherwise setup is the same as Infinity, and prices seem similar.
