Apple has recruited Verizon for the iPhone 5 launch after having soft-launched a Verizon iPhone 4 a few months ago which has already accounted for about a third of all iPhone 4 sales going back to the device’s launch last summer. That tells you the kind of momentum the iPhone already has on Verizon, and just how overwhelmingly popular the Verizon iPhone 5 will be. There’s also talk that the iPhone 5 could expand to the other long-shunned carriers. Apple is also set to navigate the tricky 4G and 4G LTE waters with the iPhone 5 one way or the other, and must use the device’s launch date as a platform for explaining directly to the mainstream public why it is – or isn’t – going the 4G route with the iPhone 5.
