I was in the Silverdale (Auckland) Telecom store (just refitted) today and they had a interesting promotion going..
The deal was, you trade in your old vodafone phone + sim card and sign up to a 24 month term contract at $45.00 a month, you recieved a $300.00 credit and a bottom of the line XT mobile (there are also ment to be phone upgrade options coming soon i.e spend $$$ and recieve this phone.
I thought it was a very good deal I was only there for a couple of minutes and wasnt to find out anymore info.
They also had 6 mobile phones on display (i think these are the right models...):
Nokia E71
Blackberry bold 9000
(Some other type of blackberry phone i think)
Sony ericson c510
palm Treo Pro
(SE walkman slide phone possibly W705)
Also there are meant to be 15 Devices available at the launch..
