Apple iOS 12.5.3 stable version is official – really old iPhones can upgrade


It is quite interesting to see that really old smartphones get some sort of support. For Apple, its iPhones never really get old. We say this because a lot of people are still using the iPhone 6 series that was released in 2014. It is not common to see such old Android devices with users. Interestingly, Apple has given such old iPhone users something to smile about. In the early hours of this morning, in addition to the official versions of iOS 14.5.1 and iPadOS 14.5.1, Apple also released the official version of iOS 12.5.3 update. This update is suitable for old iPhone models that cannot install the iOS 14 update.
