Apple has warned iPhone 5 users to update their software before the weekend or face losing access to the internet.

According to Apple, users who do not download iOS 10.3.4 by 3 November would be locked out of features that rely on the correct time and date. This includes the App Store, email, web browsing and storage service iCloud.

The update is necessary due to the GPS time rollover issue that began affecting GPS-enabled products from other manufacturers on April 6, 2019, according to the company.

Those who own iPhone 4S and some older versions of the iPad should download the latest software to ensure GPS services keep working.

This includes owners of the first generation iPad mini and fourth generation iPad and older.Owners of newer models are not affected. WiFi-only models are also unaffected.
