After a very slow start unbundled connections seem to have gained the momentum of a jugernaut. The Office of the Telecommunications Adjudicator report for December 2007 lists the UK as having 3,748,000 unbundled LLU lines in the UK.
Additionally 4.53 million lines use a wholesale line rental (WLR) product and a further 5.89 million telephone numbers have opted for carrier pre-selection (CPS).
Yes and its a nightmare moving from one to another still :-(
