anatoki: raytaylor - As I said above, you can keep your existing handset if it's CDMA. No need to lie to us.
I guess you could get the free phone, sell it on trademe and then ask us to NAM your old handset.. Personally I'd prefer to just get the $200 voucher. :)
The other issue is with an ESN swap is you would need to change the MDN/MIN on the TCL supplied phone if you were to sell it on Trademe or even give it to someone else, and unless TCL uses the same Nokia programming codes (possible) as Telecom do then on-selling the phone is pointless. Part of the beauty and pain of CDMA networks is locking the handset to the provider who supplied you the handset. Yay for GSM and Telecom going down the W-CDMA UMTS path, just a shame they will be running on 850Mhz, so most of the existing Voda handsets won't work on the new Telecom network.
And yes I have seen Telecom said they will keep the CDMA network until at least 2013 or so.... But time will tell once W-CDMA goes live as you can bet Telecom won't be offering CDMA phones anymore.
