I just happened to come across the maps for DC-HSPA+ coverage on VF. They are dated April 2012.
I don't have a clue about the technical stuff but gather it is pretty fast.
I was surprised and vaguely amused to see that a chunk of the waterfront and CBD in Wellington, our capital, does not have coverage, but an apparently random patch of sea in the harbour does!!
