Uh. No. The iPhone 5 was sold out here for weeks after launch last year.
To the OP - For the iPhone 4, I showed up at 10 PM the night before and was 32nd in line. I also received one of the last two "walk-in" phones that Apple had. THere were literally thousands of people in line. It snaked the entire width of a mall hallway and down two and a half full length mall hallways by the time I left at 1 PM the next day. Yeah, it took that long to get through the store at line position 32.
Without pre-orders, I fear this year will be far worse. This is of course dependent on where you are. I am in central florida. There is one mall in the area that allows people to line up, the others do not. The ones that do not result in a mad trample-inducing dash to the door from across the street when the mall opens. I avoid those situations.
