Phone activation is not equal to warranty start. Both are normally completed during the iTunes activation process but there were many issues and not every transaction completed.

Did you use the new SIM and did you use iTunes for the activation?

Yes and yes. I also recieved emails from at&t and apple that my phone was activated. Maybe the system hasn't caught up yet. Have you checked your status yet? What is yours saying.
