The biggest difference between the US and International version is... the US version is a dual core phone and the international version is a quad core phone and doesn't support the AT&T LTE network. I should say, it is not flashed the get the AT&T LTE network. But, truthfully, it doesn't matter if it supports the AT&T LTE network or not if you're going to use it on ST. You won't get the AT&T LTE network anyway.
