This is a big deal for AT&T customers (the majority of iPhone users) who have ordered an iPhone 5 or will be waiting in line for one tomorrow. If you buy an AT&T iPhone 5 it's not going to support LTE on any carriers outside of North America! Don't believe me? See this: http://www.apple.com/iphone/LTE/ I hope you don't plan on traveling much. Just one more reason I am fed up with carrier lock-in and am content with waiting for the unlocked version.
