whats with all of this customs and taxes talk? cant you just take it as hand luggage and pay nothing? why do you need to pay taxes..etc?

you are not following the topic. In my case im not able to go to Canada (as well as thread starter). So the only option to get an unlocked device is to buy it from apple.ca , get it delivered to my Canadian friend in Vacouver and ask him to mail it to me (to Texas where I will be present for 3 weeks) by ordinary post service.
Thus we'd like to know how reliable this option is . Are there some customs , duty fees etc
