I'm curious about the underlined part. When I've ordered iPhones or called customer service, I've been routed through Business Customer Care. I think this is due to my corporate discount. This "should" mean my access charge will be $15/device instead of $20.

If anything is like how it was in the past, that applies to "CRU" (corporate responsibility user) lines that a company pays, while anyone with a business discount who pays the bill themselves is considered an "IRU" (individual responsibility user) and probably will have a device access charge of $20. This is a lot like the prior instances for CRU business accounts paying $35 instead of $40 for devices still under contract, but with newer plans.
I'll still be curious to see as I have a IRU account for myself personally with a business discount and manage the CRU accounts for work. Hopefully these new plans will benefit one or the other.
