I arrived at the Northstar Mall in San Antonio around 6:45am.....the line was already really long to get in the mall.
Eventually, shortly after 7, they split everyone up into two lines, those with reservations, and those on stand-by.
The reservations line was much longer than the standby line. It was very muggy/humid and it was very uncomfortable outside. But the Apple employees were very enthusiastic and friendly. They brought by carts with water and breakfast tacos.
Around 8:00, the store manager counted along the standby line and told everyone beyond a certain point that they most likely would not even get in the store before closing, so a lot of people in the standby line gave up and left. He said they would let in 1 standby person for every 10 people with reservations.
Because it was so hot, they directed the lines to a different mall entrance and got everyone inside the air conditioned mall. Once inside, we were brought more water and snacks, and were told that Schlotsky's deli sandwiches would be offered soon. At 11:30am, I finally had my iPhone 4. Almost 5 hours in line. It was fun, but I'll probably never do that again. I would have had it delivered, but I'm in San Antonio temporarily and they would only ship to my billing address in Washington State.
