Apple has asked its iPhones users to update their existing iOS version to iOS 10.3.4 by November 3, to continue using functions like iCloud and the App Store.

In alerts sent out to iPhone 5 owners by the company, the iPhone maker warns failure to update the iOS would result in discontinuation of features/services like App Store, iCloud, email, web, and other services.

“Starting just before 12:00 a.m. UTC on November 3, 2019, iPhone 5 will require an iOS update to maintain accurate GPS location and to continue to use functions that rely on correct date and time, including App Store, iCloud, email, and web browsing,” the company said in a statement, adding, “this is due to the GPS time rollover issue that began affecting GPS-enabled products from other manufacturers on April 6, 2019. Affected Apple devices are not impacted until just before 12:00 a.m. UTC on November 3, 2019.”

Other than the iPhones 5, fourth-generation iPad with Wi-Fi and Cellular would also be required to update to latest iOS 10.3.4.

Meanwhile, the company has also asked users of iPhone 4s, first-generation iPad mini Wi-Fi and Cellular, iPad 2 with Wi-Fi and CDMA Cellular, and the third-generation iPad with Wi-Fi and Cellular to update current iOS to iOS 9.3.6.
