I woke up at 8:30 am, shaved and showered, and left my house at 10 am. Got to the AT&T store (which is only a few blocks from my house), walked right in, and within literally 30 seconds I was standing at the register checking out with a 32gb iPhone. Would have been in and out in about 5 minutes total, but their computer system was bogged down, so it took almost an hour to checkout.
Had the same thing happen last year when the 3GS came out, except that day I didn't make it to the store until after 6 pm because of work. Still was pretty much right in and out though.
While waiting today, I was bs'ing with the sales girl, and she said there was a small line before they opened, but no big deal. Said the first people lined up about 4 am...they backed their truck up to the sidewalk, set out lawn chairs, a cooler with drinks, and had a tv in the bed of the pickup.
They were setting up tables in front of the store and handing out water, oj, soda, coffee, and snacks and pastries, but there was hardly anybody around by that time....they should have had it there for the people waiting when the store opened.
