FUD. . .
At a guess I would say that Vodafone is just scared and pissy. First they told us that they would have 3G everywhere in NZ by mid 2010. Then Telecom say that they will have their new GSM network up and running by May 31 2009, and Vodafone releases a statement saying theirs will be up and running May 30.
Now they are taking it to court due to possible 'interference'?
FUD indeed.
