With the iPhone 4 launch less than two weeks away, we are continuously getting new information about the launch. A leaked internal document sent to AT&T store employees explains the procedure for launch day, including a 7AM store opening. While we are still unsure of when other stores carrying the phone (Apple, Wal-Mart, Radio Shack, and maybe Best Buy) will be open, we can confirm that all AT&T COR stores will indeed be opening at 7AM to sell the phone on launch day. Not only that, but AT&T employees will have a “cool” shirt to wear that morning.
