I have a few damages on my Image S4i's and I am wondering how I can use my warranty. I have not physically, accidentally or personally damaged the product, maybe because of it started to wore out or because of the durability, I'll have a few photos to show if it is nessessary. Currently, I worry more about the warranty requirements. Since I did not register my Image S4i's anywhere (I bought them around late August), I do not have the receipt from the Apple store and I live in Canada (bought them in the US), is it possible to send my product for repairs in anyway? Do I require to register my product anywhere and do I need to reciept?
