Old iPhones could stop working on Sunday, Apple warns

SAN ANTONIO – Apple is warning users of old iPhones that their devices could stop working this weekend if they don't update their phones' software.

iPhone 5 users will be required to download an iOS update by midnight on Sunday to continue using their mobile device.

"This is due to the GPS time rollover issue that began affecting GPS-enabled products from other manufacturers on April 6, 2019," according to Apple's support website.

Users who don't update their software by midnight will be required to back up and restore their iPhone 5s using a Mac or PC as the over-the-air software update will no longer be available.
