Same here. Bummer. I did order it very late in the day of preorders because I had to cancel my stupid AT&T order first and took forever to get through, kinda worried.
Yeah, I'm a little anxious but it won't be the end of my world. I ordered at 2:01am CST, so right away! Order confirmation email said delivers by 9/19. I'm still holding on by a very thin thread, holding out hope! LOL.
You guys need to stop worrying. I also ordered late in the day for the same reasons (had to cancel AT&T order first). Both my phone and my wife's phone have just shown up in the support profile. I can't find any tracking reference yet either, but I remember going through the same thing with the 5. I bet if you check back tonight/tomorrow, your phone will also be on the support profile.
