we've had it with Vodafone coverage issues, dropped calls, stalled data and what not and have finally managed to get out of our contracts without ETC's. 
We have 10 iPhones that we are bringing over to XT, but it appears the $600 credit promotion is over - i queried XT as to whether they had any similar promotions to reward us coming over, but they only have standard $266.66 porting credit which wont cover the costs Vodafone are likely to charge us for the handsets (waiting to hear how much that will be).

Anyone out there know of any "secret" deals to ask for?

also any horror stories of moving from Vodafone to XT?
or XT coverage issues?
(mainly Takaouna & Mt. Eden auckland)
