"Mobile provider 2degrees plans to open more than eight retail stores in the next year as it gears up to launch its 3G service and offer post-paid plans.
The firm is negotiating leases for stores in central Wellington, Auckland and Christchurch and eyeing up potential sites in Hamilton, Palmerston North, Tauranga, Nelson and Dunedin.
It has signalled its plans to offer a 3G service and to start signing customers up to contracts rather than offering pre-pay services only."

So we need to wait a little longer, unless 2D is willing to open some kind of trial of their 3G network for geekzone users

Cheers
