The funniest part of this is that it's JavaScript.

Yup

People said it in the other threads, but this is just boring regulatory processes at work. It's just a story because popscience type outlets ran with the word radiation

Never underestimate the clickbait potential of the word “radiation.”

The word "radiation" has unfortunately been commandeered by idiots to mean "TOXIC MAGIC AIR". Lightbulbs radiate (produce light).

In this case they're 100% just reducing the gain on the phone's signal strength. No harm prevented. Purely regulatory.

if i had to guess, it's setting power limits on the cell/wifi radio chip.

Probably going to throttle it a bit. The only issue is that the power level of the radios in the phone make it a little too warm when you have it to your face.

Yes it’s a special update for that region alone. Apple does this quite often when a country requires special treatment. It rarely makes the news because well it’s not really news.

Probably just dial down the power emitted like some high end routers let you do in settings. It’ll make the cell service weaker but I don’t think Apple cares much for a device they no longer sell or manufacture anymore.
