Best Buy will be the only store to carry the iPhone 3G other than Apple and AT&T. Best Buy has snagged an "exclusivity" deal with Apple for the iPhone 3G (exclusivity excluding Apple and AT&T stores). The phone will be available in all of Best Buy’s 965 U.S. stores as of September 7th. This should be a great sales boost to Best Buy, whose sales have been in the slums lately with the weak economy. Although their profit margin on the iPhone 3G is rather low, and the hype is starting to die down, there is no denying that fact that this will be a great thing for Best Buy, Apple, AT&T, and of course, you.
