As you may recall, as early as July, Apple released a rare bug fix update for its earlier operating systems, iOS 10.3.4 and iOS 9.3.6. That’s because the GPS network has been adjusted and the upgraded system has been fixed to help keep older iPhones and iPads accurate.
However, the iPhone 5 is more problematic than the average device, so Apple is sending an alert to iPhone 5 owners that their phone must be updated to iOS 10.3.4 by November 3. If iPhone 5 is not updated in a timely manner, the device will not function properly or THE OTA upgrade will not work because services including connecting to the Internet, browsing in Safari, email, iCloud, and the App Store may not be healthy.
Owners of the iPhone 5 will see a fairly large dialog box appear on their phone, making them aware of the importance of updating. Apple also released a support document to explain the details further.
If the user misses that date, they will not be able to make OTA updates and iCloud backups because the phone will not be able to connect to the network. In this case, the user will need to connect to the computer and use iTunes on the PC or Mac to restore.
GPS errors will begin affecting Apple’s hardware, such as the iPhone 4S, iPad 2, the retina display and the fourth-generation iPad, before midnight UTC on November 3. For these devices, not updating means that the GPS feature will stop working, with much more serious consequences for the iPhone 5.
To update to the bug-fix version, simply go to The Settings->software update, the sooner the better.
