um Warranty. Does it sound familiar? Think about it man. If I were you, i'd add applecare. If anything happens to the ipod (ipod nano, touch, etc.), usb cable, earphones or anything that was included when you bought it originally applecare will replace it for free I believe. I had my earphones replaced free with no questions asked and they arrived in 3 days. Well worth it
I thought you had to call a number to register applecare?
I'm just afraid that if I register it, it'll restrict me to itunes sites, eg, I buy music in canada but buy my movies from itunes US store. Would registering it restrict where I can buy music/movies from?
i was under the impression you're physical location limits you to where you buy movies and music from.
have you successfully purchased music from a store other than the canadian store?
Since you have two Apple IDs, you're probably going to be better off either not registering at all (to avoid confusion) or registering only with your Canadian account. Do not try to register it with both accounts - this is likely to fail.
That said, unless you have AppleCare for your iPod there's no real reason to register.
