I've read and heard reports that the US carrier variants of the S7 and the S7 Edge are locked and can't be rooted. I have also heard that the international version (based on the Exynos chipset instead of the Snapdragon one) is unlocked and therefore rootable. The question is where can I buy the international version of the phone? If I buy an unlocked version of the phone from Samsung's website, will it be the Exynos-based international version, or will I need to make the hour drive to Toronto to buy the device instead? Thanks!
