These devices are supported, but they are not fully updated and have not been fully updated. However, since the latest generation and latest updates are expected to be updated, I have to inform you about them. And I have to tell you clearly. There are many things to understand before buying this, including iOS 27, and there are also things that will happen sooner than later this year. And they are already happening.
