Apple has finally released iOS 10.3.3 to the public, meaning that AWT contributing editor Marty Edwards was correct in his prediction on AWT TV Episode 15 that it would be released this week!
The update just "includes bug fixes and improves the security of your iPhone or iPad. Like all other system software updates, 10.3.3 can be installed by launching Settings, tapping on General, and then tapping Software Update.
For the iPhone 7 Plus, the update weighed in at 137.6 MB. This will most likely be the last update to iOS 10 prior to the release of iOS 11 in September or October.
