after posting my last message, I walked to the SF Apple store. (its just a 15 minute walk away) Even though the lady on the phone said that they were sold out of all models, I asked one of the Apple employees, and he said that there were iPhones still available, but the wait was going to be 2-3 hours. (it was a little after 7 pm)
I proceeded to the back of the line, but there was another Apple store employee standing their saying that no more people are allowed to join the line. (because they wouldn't be able to service anymore and close shop by 9pm)
I get off work around 6pm each day which is probably around the time that they either sell out or cut off the line. I think the only way I can get one is if I go on my lunch break. I wonder how long the lines are at noon or 1pm. If its less than 2 hours, I'd definitely go on my lunch break.
