I saw that today and I dont know. Different frequencies I guess. The post here on AC said that the Korean version of the new LTE equipped was not north american compatible. Mathematically I know that four is twice two, but Im guessing the differences in speed or performance are not noticeable. I may be called a heretic, but I dont see that big of a deal of 4G LTE v 3G. Granted, I use my device mostly for business and dont use it for much media related tasks (except streaming radio stations, sports and baseball games), but all that stuff works fine over 3G. How much faster is my mail going to show up? This morning the internet in my mountain house went out and I listened to the morning news on my phone, streaming on EDGE. It worked just fine.
