All Apple says is, This update provides important bug fixes and is recommended for all users.Note the absence of the words security fixes, so we know that its not about cybersecurity, but entirely about putting right things that werent working quite right. Apple is tight-lipped about exactly what these might be, but the absence of security elements means those who dont want to upgrade can feel more relaxed about not doing it, assuming theyre not experiencing problems with the iPhone.Note that Apple also stresses that its recommended for all users which suggests the fixes are not solely about Apple Intelligence as that only applies to users of iPhone 15 Pro, 15 Pro Max and the four new iPhone 16 handsets.Ill be exploring whether you should upgrade to iOS 18.2.1 on Tuesday, Jan. 7, in response to how users react to it.
