Ok.... Please try to understand the issue I have. I can login to Facetime just fine. No errors about registration or GUIDs or Apple IDs. In fact, Facetime will be perfectally functional for the first, oh... I'd say, minute or two and then ceases to receive and make calls. Turning off and then again on Facetime corrects the problem but again for just a short while before it borks again.

SN is replaced, latest chameleon installed and my ethernet is recognized as built-in.

So the issue has nothing to do with PCI roots or anything like that. I think it's because of a missing cert or backgroung processes (pushservice, imagent, marcoagent and ftmonitor) not working properly.
