Does anyone know if and when Vodafone NZ plan on bringing these devices to NZ?

I really like these smartphones though from the current release in the states I have heard alot about problems with the quality of the sound and camera. Some of these issues have been fixed however it seems pot luck if you purchase one of these phones from overseas as to if the phone you get has the updated firmware.

If anyone has any ideas on when they will be available in NZ or how to import one I would be very grateful.
