Apple’s i OS mobile operating system is less prone (though not immune) to malware and viruses, compared with other platforms, like Android.
Still, it’s always good to keep an eye out for anything that seems fishy, like misspellings in the update message.
Google and Microsoft also make carrier-related changes to their Android and Windows Phone devices, respectively, but they’re folded into a more general software or maintenance update.
Let’s say you’ve been using an unlocked i Phone on AT&T’s network and decide to switch over to T-Mobile.
Your i Phone will need to update its carrier settings so the device can work with the new provider.
Unfortunately, getting answers to these questions is much harder than it should be.
Unlike major operating system updates, there isn’t a lot of information or messaging about what carrier settings updates do, where they come from or how they impact your device.
