Apple commits to at least five years of security updates for iPhones
In order to comply with the Product Security and Telecommunications Infrastructure (PSTI) Act in the UK, Apple says it will provide security updates for iPhones for a minimum of five years.
While Apple has not previously abandoned iPhone users and left them with insecure devices -- in fact, the company has been known to release updates for very old handsets in extraordinary circumstances -- it has never previously committed to any particular period of support.
