Last year to boost its services business Apple gave all customers of new products a free year subscription to Apple TV+. That offer is still valid today even for customers buying the new iPhone 12 and iPhone 12 Pro. However, as 9to5mac notes, if you redeemed your free year voucher last year with the iPhone 11, you won’t get another free year with your iPhone 12.
Additionally, starting on October 22nd all new product purchases come with 3 months free of Apple Arcade. Like Apple TV+, Apple Arcade will automatically renew after the trial finishes unless canceled prior.
