important! Apple suddenly released iOS 9.3.4: must upgrade
Not long after the release of iOS 9.3.3, Apple suddenly released the iOS 9.3.4 update earlier today, and stressed the importance of this update.
In the update of iOS 9.3.4, Apple stressed that if you are already a user of iOS 9, then this upgrade must be updated, because this is an important security update.
In addition, iOS 9.3.4 also fixed the vulnerability of the previous Pangu iOS 9.3.3, so jailbreak users ignored this upgrade.
This update, users can still upgrade through OTA. I don't know if Apple will release a small update to iOS 9 before the official release of iOS 10.
