Considering the sitefinder site was next to useless as it was so out of date this is pretty futile, last updates were 2005 to 2012, so it won't be showing any 4G sites, for example.
That's brilliant, I've missed sitefinder so much for finding where some sites still are. Only problem, this website has completely forgotten about Northern Ireland's sitefinder data So it's rather useless for me
Sitefinder was rather out of date - I think T-Mobile stopped giving data in 2005!
Plus as others have said, no mention at all of 4G, some sites will have been decommissioned and some sites will have been upgraded to 3G/4G (in the case of the 2G sites).
