2 or 3 weeks ago I got my first call from "Comcast", which I do not have a contact for. I was surprised because I didn't even know the system as a whole was capable of that. I've never seen a non-contact name come up in my phone UI before, only phone numbers, or phone numbers mapped to my contacts.

On the plus side, when I get a call from a textual non-contact number it's a heck of a strong signal I don't need to pick up.
