Oh wow for that price of 680 then I will get me the international version! It is true about the upgrade. Might as well go quad. I to also use wifi all the time so lte is not a neccesity. Thanks for all the info guys!
You also wouldn't get 3G with the International version, so that would make no sense at all. The Krait chip out-performs the quad-core anyway, so why are you worried?
