Standing outside in the elements all night in order to pick up the latest iPhone is surely one of the great traditions of Apple fandom. And if you're inclined to do so for the upcoming iPhone X, Apple is actively encouraging you. 

According to an announcement on Apple's website, the new phone will be available for walk-in customers in 55 countries on Friday, November 3 at 8am local time. You're "encouraged to arrive early."
