I picked up my 8300SD yesterday from a Rogers store. When I set it up today, it said it was not activated and to call 1-866... Since Rogers is not open today (which is a good thing) is there any other way for me to activate it or do I need to wait for tomorrow?

Never mind. I just found the option after logging in to rogers.ca.

There is an automated way to do it over the phone too. Kind of hard to say how with their new voice response system, but I believe you say "service" to get to that menu (or maybe it's "repairs"??).
