Good to know

The catch, and what this leaves out

0% isn't free if it keeps you upgrading. Apple's installments charge no interest, but a payment that never ends is still the trap.
A lease costs less a month because you hand the phone back. After years of payments you own nothing.
Carrier deals often spread credits over 36 months and need a pricier plan to qualify. That extra plan cost isn't counted here.
Trade-in value, cases, repairs and sales tax are left out for both people. A phone kept 4 years may need a new battery.
