Reminds me of that old Mitch Hedberg joke, "You will either hate us or love us... or you'll think we're ok."
Were you the kind of kid who had their Christmas morning ruined because you had to wait 364 days for it to happen? Everyone groaned when the AT&T exclusivity agreement was announced, but widely understood that it would be years before you could get the phone on another carrier. I'd argue that while it was a polarizing move, publicized exclusivity actually helped the sales of the iPhone. You either accepted that you'd have to use AT&T and got the phone regardless of the service, or you didn't. Anyone waiting with baited breath for a second carrier in the US was either ignorant, stupid, or both. The options were clear. Now that exclusivity is about to be over there is a second wave of adoption coming. Why? Because the things that made the phone worth buying to begin with are still there, and the only deal-breaker for most people is going away. Everyone who "needed" an iPhone already has one. Everyone who "likes" the iPhone is about to have it be an option.
I would love to see the facts supporting your hypothesis that, "AT&T gave up its exclusivity deal with Apple for the iPhone back in the spring of this year. Verizon and other insiders had to have known well in advance that they were going to. They should have been ready for a release in July, at the latest." You're making assertions about the strategy for the next phase of one of the most popular consumer electronic devices ever, and you're backing them up with the word "should."
