No, the carrier leverage did not come from network policy, it came from sales-channel. That is to say, in those days one way or another every device passed through a carrier's hands before reaching the customer. So carriers controlled pricing, and to a large degree, marketing. If they didn't like your device they would refuse to sell it and then you were stuck.

Unlike RIM or Palm, Apple could realistically choose not to sell their device at all, or at least not sell it for a while, and so they were able to break the carrier oligopsony. It also didn't hurt that Steve Jobs was, well, Steve Jobs. A one-of-one business negotiator.
