It doesn't really matter, though, since though I understand that the new iPhones include real-time voice-chat, I never use it. There are only three numbers I ever accept voice calls from, and one of them's a robot, but sometimes I'm curious.
How is it that the cell companies still think it's a good idea for the protocol to not include the text of the subscriber name? Land-line CID had that, but cells never have. It's weird.
