Local Council's and Whiners can be to blame also
I'm still waiting in the lowly backwater of Hartlepool for O2 to pull it's finger out after getting it's second planning approval for a 3G mast installation, a year after the approval was given.
Of course the first planning application had the kibosh put on it by some Victor Meldrew type who thought it didn't look very nice.
I sincerly doubt that the other parts off the UK are less enfranchised with this outlook.
Mines the camouflaged tree looking 3G coat.
