is it open at midnight?
or like normal time when the store opens?

and how early do you think I should line up?
haha well I live in Los Angeles soooo yea you're right about that I better line up pretty early. I wouldn't be surprised if there were people lined up a couple days before it opened.

8 A.M. local time on July 11.

Unless you go to apple store on 5th avenue in New York, I don't think there will be monstrous line up (depending on where you live). Check your apple/at&t store on July 10 at 10-11pm to get an idea.
