How big is you're exchange?
Alot of 'white areas' where the market wont reach will be able to see their local CC LBP in a few months then tenders and work starting towards the end of the year, so there is improvements on the way.
I would hope BT is fast in my area, as they have just finished enabling a exchange for 21CN and FTTC, another exchange had a 21cn rfs date of the 31/12/2011 though not showing as enabled by sam knows.
If it is done then theres another 2 exchanges to go before my exchange will get enabled 31/01/2012 and 29/02/2012. Though my exchange date is not till the 31/05/2012 seems quite a gap.
