Initial setup doesn't go through on Wi-Fi, saying the problem is under investigation and team is still doing testing on it.
Apple says that "there is a known issue for iOS 16 that may impact device activations on open Wi-Fi networks."
Apple noted in the memo there are no current official fixes and that support staff should "not create a repair [case] for the issue."
Unfortunately, the bug is untimely, as customers worldwide begin receiving their iPhone 14, iPhone 14 Pro, and iPhone 14 Pro Max pre-orders.
For new iPhone 14 customers, an available iOS 16.0.1 update fixes an issue with activation and migration during setup.
If you're facing issues activating your iPhone 14 out of the box, you may need to restore it with a Mac or PC to iOS 16.0.1 to fix the bug and fully activate your new iPhone.
In a support document, Apple tells new iPhone 14 and iPhone 14 Pro customers that "iMessage and FaceTime might not complete activation."
