Picked up a 32GB iPhone 3GS in Black on Friday, June 26th. Lovin' it!
I'm pretty sure all Apple and Att stores were notified and clearly are aware of what is happening with the whole 6pm thing. It pisses me off though cause you can call one guy and he'll tell you everything you know, but when you get another guy he'll just say "call back later....like the day before". My Att was nice though;-)
June 29!
I don't think you'll find an iPhone at a Cingular store. Only AT&T Wireless Corporate stores will carry the iPhone. The new CEO doesn't want the iPhone to have any relationship to the Cingular brand name. So don't be confused...if the store says Cingular, keep away!
Where I work my Best Friend is the Scheduler, and because she knows I want this phone she gave me Thursday, Friday and Saturday off just because she knew I might request the day off or call in sick, so she rather I already had the day off that way I wouldn't get in trouble.
She told me she gave me Saturday off also because she knew I would want to spend the whole day playing with it and work would just be a distraction for me, haha.
