surfisup1000: I just went through the rigorous helpdesk procedure , firstly with telecom, then apple, then back to telecom and finally got through to someone who knows what is happening.
Telecom are aware of the issue and they have network people investigating. They think it might be related to ported numbers and the device is not communicating to the apple server.
And, hopefully the issue is fixed sooner rather than later (in their words) . .. they will send me an sms with details at a later time.
Great to hear you got a good response with some good information. Let us know if you get more information from TNZ.
