I'm not attacking you, don't attack me, please. You can listen to what I'm saying or not, it doesn't matter to me. Here is my reasoning, though:
Money. Plain and simple.
Take this scenario: Verizon releases the iPhone 4, and there was much rejoicing because finally they could have a great phone on their network (AT&T works great for me, but Verizon did too. I have no complaints either way).
Fast forward 4 months: Everyone on Verizon is happy with their iPhone 4, but Apple holds a press conference saying they're releasing the iPhone 5. The World oohs and Ahhs at the fancy new features and the shiny new look. It will be available, they say, on whatever date. BUT, they say, Verizon won't carry this phone.
As a Verizon customer, even IF you had the iPhone 4 from February, how would that make you feel? To know that every other iPhone user in the World had access to this shiny new piece of technology except you. If it were me, I'd be pissed.
In the end, Verizon will release it because by then all of the friends of people who got the iPhone 4 will have upgrades available and will want one.
Do I have facts to back that up? No news stories, no press releases, just common sense. It's the same thing with the Droid and the Droid 2. It's all about the dollar, plain and simple.
