As far as I can gather, Siri in it's beta form won't have all the features for every country. So certain countries might get more features for Siri compared to others.
As far as your upgrade goes, if you are fully eligible, then yes overall you will be paying the $159 plus the $35 admin fee. Just keep in mind the $159 is after a $50 mail in rebate so your bill will show $209.
I'll be very surprised if it'll be so limited here compared to the US. Did anyone have any luck with contacting Apple Canada regarding Siri features?
I hate the mail in rebate bs. I guess i'll get my $50 after 3 months..
So i'll be paying $245 upfront for the device? pretty ridiculous.
