Did you have to trick the date because of the 24hr restriction on checking AT&T for updates? I didn't have to change the date and my phone is downloading the update also.
Downloading in California right now. 565.7MB. Huzzah!
No time trick needed.. I did AT&T software update, it said I couldn't check for 18 hours, and then a minute later I got a popup that said Update Downloading. Go figure.
Still nothing here in Indiana. I changed date to the 10th, but it's been checking for update for the last 15 minutes. I'm over it. - I'll get it, when I get it.

For the ones who are having problems updating through the AT&T Software Update, you can do a manual update, install on a computer and then run it to update your phone.
