We'd be happy to have ya.. :P...
But in all seriousness.. I do agree with John/Steve... No mobile network has nationwide coverage. Just need to find a network that works for you coverage / price / feature wise... and deal with the downsides.
In all fairness, Vodafone coverage is excellent for the majority of people. I find what is lacking is the signal strength. Just going through the Victoria tunnel on my (same) phone with XT I get full reception. Proximity may be one factor but it would seem then that my phone is never near "any" Vodafone towers - Farmers on Lambton Quay, Pak n Save in Mt Albert or anywhere I'd expect decent reception ... or perhaps Telecom likes building their towers near tunnels and populated areas :P
My suspicion is this mostly has to do with the volume of network traffic rather than positioning.
