Is the iPhone the major revenue driver for any carrier? What matters to the carrier is the plan they can sell you, not the price of the phone you're using with that plan. I could believe that iPhone users on average have more expensive plans (due to being less price sensitive), but in most markets Android has the dominant market share.

Edit: I suppose carriers are regional, so the iPhone might be the major revenue driver in the US, but Android can't be too far behind. Neglecting 40% of your userbase doesn't seem like good business.
