It seems a number of exchanges have been updated on SamKnows to show FTTC status as 'Enabled in Some Areas' (Wrexham for instance). My phone number (not in Wrexham) shows as FTTC enabled on SamKnows but not available on the BTWholesale/BTinfinity checkers. I'm guessing the BT checkers are more accurate, but where is SamKnows getting it's data from? Could this indicate an upgrade sooner than expected?
It's also only just been updated to show ADSL2 enablement from back in March.
