Yep, this is making the rounds on twitter. I'm not there yet either, so I can't confirm either. However, having had horrible experiences with AT&T in the past, I just looked up how to turn off 3G on my cell phone (since I don't have data plan on it anyway, I use iPad for data.) Turns out mine and probably others can turn off 3G, just typing code numbers in on dial screen. Even if you don't have iPhone or similar you might try googling "phonemodel disable 3G" to see if it works for you. ("You" being anybody, in this case.)
I'll try to remember to update after being in Vegas for a few days, it should be pretty clear if this helps - in the past, like others I've had missed calls and texts often came hours later when I stepped outside.
