Sorry for butting in but I have a simular problem, I too am trying to get sky broadband, the results fron the prodigy site are

Line status

This line has a Shared Metalic Path Facility (SMPF) on it - either the broadband or phone service utilises an LLU service while BT provides the other service normally.

I have 2 phone lines in the house and on the one I checked I have never had any internet provider on it, we have been in the house for about 7 years, the broadband I have at present in on my other line, how can I get sky broadband

Thanks for any help.
