Having retired my iPhone 6 for the IPhone 15, i am quite pleased so far. These devices can last for many years, so the cost is justified. I have more confidence in Apple than most other companies for user interfaces and security.
Great phone. Noce improvements over the 13. ATT is super helpful ONCE YOU GET THEM... the automated 'help' is lousy, but I've had good luck with the humans, once you can get to them.
