Cabinet went in about August 2010, checker said 30/09, then 31/12, then 31/03, then changed t0 03/02/2012 and that was the day I ordered Infinity, installed just over a week later on 11/02
A work colleague who live a few hundred yards from me, same exchange, different cabinet (which went in about the same time as mine) was able to order about 6 weeks before me. Another colleague, same exchange, roughly the same distance away, still cannot get fibre now over a year later.
