How early should I go to the apple store on the 21st to get an iPhone 5?

It says they open their doors at 8. How early should I go so i can get one. I don't want to wait in the line for a long time for no reason. Is 6 early enough? Anybody have any expcriances with waiting in line for the newest apple product?

Added (1). I know I'm going to be standing in a line, obviously there's going to be people camping outside the store for a couple of days before it comes out. I just want to know how early to go so I'm guaranteed an iPhone 5

People are gonna be camping out for this replica phone… Just wait till the 5s comes out or 6. Doesn't matter how early you go, you are going to stand in line.

  • Will the iPhone 5 be delivered on the 21st, or shipped? Has anyone pre ordered the iphone before? If so was it delivered on the date that they said or was it shipped out that day. Basically I want to know if i pre order tomorrow, will Apple ship it out on the 21st, or acutally be at my door on the 21st?
  • Why do 20th century born people think they had a better childhood than us 21st century borns? People born before 2000 think they had a good childhood. How stupid are they? The 20th century was the most violent century of all times so you can get killed or hurt back then. As a 2000 born, I think I can easily say the 2010s dominates the '90s, the '90s wasn't good anyway. The '90s sitcoms were stupid, the '90s music sounded like a man farting on a public restroom, movies were boring, games were stupid, no iphones/social media existed, etc.
  • Why do 20th century born people hate the 21st century due to 'social media' when they're the idiots who created it in the first place? As a 2000 Born, I just learned that people born before (20th century borns) are very critically and mentally-impaired when it comes to nostalgia. These dummies now say that my birth century sucks because of social media and the iPhone invention. Will guess what? These were invented by 20th century borns and they're the reason why my birth century is hated.
  • Where is the best place to buy an iPhone 4s: the Verizon store or the Apple store? I don't have an upgrade until January but am looking to buy an iPhone soon. I've been looking at the various sites and saw that there was a huge price difference between the Apple and Verizon stores. A rep at the Verizon store told me I wouldn't even have to change my existing plan, but just pay the $449 for the phone. Why would I buy an iPhone 4s from Verizon for $449.99 when they're sold on the Apple website for $99?
