I have the same customs message as everyone else. I've had it since 11:00am.
I called UPS a total of three times today. The first two times I was very quickly reassured that I would be receiving it today.
Once I called after 7:00 I got "it's going to come on Monday now" and he had no idea where it was.
Then I got a call from my local UPS centre and she let me know that my phone is still in Toronto and that it's being held up by customs. Awesome.
She said it will probably get into my city around 11:00 tonight, and if not, then by tomorrow morning I think. Since they aren't open tomorrow or Sunday, I'm looking at Monday. She suggested that I do a pickup if possible, but it won't be ready until after 11:00.
I probably won't ever order a phone for launch day again, but if for some reason I do, I'd rather drive the hour and a bit to one of the Apple stores in Toronto. But I hate crowds. So I'll probably just wait until things die down and stores have enough stock.
I'm pretty bummed.
