iPhones newer than iPhone 5 are not affected
In June of this year, Apple released iOS 10.3.4 for the fourth-generation iPhone 5 and iPad, and iOS 9.3.6 for older devices. These updates address an issue with GPS and location and are a required update.
But, if you haven't updated yet, you have to do it since from November 3rd your devices will stop working if you don't. And this is due to the reboot that the GPS system had in April of this year, which begins to be effective as of November 3.
Affected devices are all devices prior to iPhone 5 that have mobile connectivity
This reboot, which occurs once every 20 or so, makes the update completely necessary. The consequences of not having the device updated is that the functions that need a specific location and date and time to work, would stop working.
That is, the most basic functions of the device would stop working. Among them are iCloud, the Mail app, Safari, the App Store , and all the services of Apple But it is possible that apps like WhatsApp, which also needs a date, will also stop working and specific time to work.
The note that is appearing on the iPhone 5
Apple, in its informative note, focuses on the iPhone 5, which is showing an informative note on the screen, since which is still a heavily used iPhone.But the same will happen with the iPad of 4th generation and all devices older than these that have mobile connectivity.
If you do not update, you will not be able to continue using the most basic functions of the device. And basically it will stop working. But if you haven't been able to update before November 3rd, you can always make a backup copy, download the iOS version from iTunes and update the device. But the best thing you can do is update as soon as possible.
