I called my AT&T Store (located in a town with around 50,000 people), spoke with the manager himself, and he said he DID know how many they would get in but could not disclose that info to me. He recommended that I line up in the morning around the time the store opens (9AM). He also said that they would be handing out tickets at 5:45 PM to the people waiting in line. There will be the same number of tickets as there are iPhones available. My store will also have 4 registers open, and will bring people in 4 at a time to either purchase the phone or look at the demo unit.
