I was not upgrade eligible and paid full non-commitment price for the iPhone 5 during pre-orders on Friday last week but got the Oct 5th date. Do I have to cancel my order online if I decide to try purchasing in stores this Friday at the Apple Store? I know most people cancel orders online because of the discounted price they need to reset, but I don't know if I have to even though I paid full price. I thought maybe there is some limit to phone orders or something like that. My carrier is AT&T. Thanks!
