Apple designs their own chips now. but the original iPhone, used a Samsung chip.

Intel didn't just miss out on business as a fab, Apple would have used their chip design as well.

Which leads you to wonder if Apple still would have begun designing chips themselves, if Intel had put some real effort into designing mobile chips.

The acquisition of PA Semi was announced in April 2008, so it is possible discussions were already in progress by the time of the first iPhone launch

Sure, but Apple had gone public with the iPhone announcement over a year before the PA Semi acquisition.

I think it's safe to say that they had already selected an off the shelf Samsung CPU before they did the public demo of the device.
