There was an update of itunes within the last 24 hours. Make sure you get that installed before complaining! Also, because of the price drop, i think there are more people getting one than last time, would explain the clog.
I got there at 3 hours before they opened and the line was pretty short. The problem is the store only had around 50 phones. The vast majority of this line didn't show up until an hour before.
Add the fact that there are 3 flavors of the phone (most of the die-hards wanted 16gb black, including me) and things got tense quick. I thought the crowd was going to lynch the poor girl that broke the news that they had limited supply. -- Laser eye surgery rocks! I love frickin' laser beams.
