"There is an apparently new iOS 18 security feature that reboots iPhones that haven’t been unlocked in a few days, frustrating police by making it harder to break into suspects’ iPhones

I’m still on the fence of whether or not this is a good thing. In this scenario, it’s a pro. Cops or crooks can’t remove a SIM if there is no physical SIM.
