I saw this linked from MacRumors during the AT&T iPhone 18 Pro Max lockup news discussions. It was interesting to see what AT&T/Apple did to try to get ahead of the issue. So far it looks like they disabled 5G Standalone mode, possibly just to prevent a bug from literally destroying the hardware (possibly only on one batch of phones).
Apple/AT&T still haven't released any kind of statement addressing the issue other than to replace affected hardware.
