3 November deadline
"It's especially important to update your device's software before November 3 to make sure that its GPS, date and time continue to work properly," Apple explained.
"If you don't update to the newest version of iOS available for your device before November 3, some models might not be able to maintain an accurate GPS position.
"And functions that rely on the correct date and time – such as syncing with iCloud and fetching email – might not work."

Hide AdApple says that the devices will be affected just before midnight on Sunday 3 November 2019.
This is because of a GPS rollover bug that will impact the devices which rely on GPS for their time and date.
The same bug caused problems for owners of other devices in April this year.
How to check if you need to do an update
The following devices need to be updated to at least iOS 10.3.4 before 3 November:
iPhone 5
iPad (fourth generation) WiFi + Cellular
And these need to be updated to at least iOS 9.3.6:
iPhone 4S
iPad mini (1st generation) WiFi + Cellular
iPad 2 WiFi + Cellular (CDMA models only)
iPad (3rd generation) WiFi + Cellular
To check which iOS your device is using you need to go into ‘Settings’, tap ‘General’, and then ‘About’. Next to the ‘Software Version’ section there will be a number.
