Now here's something interesting. After setting up my new iPhone 5S, I discovered that I have access to iTunes Radio. This is only for the 5S, none of my other devices has iTunes Radio. I'm in Canada, so I shouldn't be getting iTunes Radio on any of my devices.
Got my 16gb grey 5s last week on the 11th. Like others have said my local carrier only had that model in stock, anything else they would have to order. Loving the touch id, haven't used my passcode to unlock my phone but 2-3 times since I set it up.
