I pity anyone coming at this thread with questions - it just gets more confusing as you go.
For how the two programs are the same:
I currently participate in the iphone upgrade program through Citizens. I have my payments set up to pay through the Apple Card monthly and I have my AppleCard set to pay the entire balance off monthly. I pay zero interest. I get 3% cash back for the phone payments.
This new program also offers zero interest and 3% cash back.
For how they are different:
The main advantage/difference would be the ability to hold $1200 for 24 months an pay off at the end - rather than paying monthly. You'd get the $36 cash back when you buy the phone, then you could invest the $1200 and if you could get 3% rate of return, another $72 on your money.
The new program appears to be an alternative that does not involve Citizens Bank and still provides the same 3% cash back. However, as others have mentioned, there is no mention of annual upgrade availability and I wonder how the program will actually work.
If I have my card set to pay the full balance every month, and I want to take advantage of the 24 months interest free loan, there are some mechanics that I'd probably need to understand.
Assuming you are a good at your personal finances, you'd want to hold on to your $1200 (price of phone) until month 24. (time value of money-wise) However, you also have a bunch of other things on your card that you'll need to pay off every month to avoid interest. So, if you have Apple music, a couple of movie downloads, icloud storage (I use my card for anything Apple gives me 3% for) and have another $50 a month in charges to pay off and you have a $1200 phone purchase, how does it keep track of the payments? Say you have $25 in charges early in the month, then buy the phone, then have $25 later in the month, at the end of the month you pay off $50 - how does Apple know that you only want to pay off the $50 that will accumulate interest in the next month, vs paying down part of your phone?
