Comment Even worse with iPhones 4/4S (Score 1) 120
I have gone through 3 iPhones 4S. Every time the same situation, the wifi option completely disappears (greyed out), and no amount of network reset etc. can bring it back. It is a well known problem with people getting temporary fixes by freezing/heating the device! It does not seem to be just a hardware problem (e.g. like the nVidia soldering), but has to do with firmware as well, since this started happening with the introduction of iOS 6 or 7 (I forget) which added some temperature control functionality.
So your wifi dies completely. It is so widespread and discussed (google for it) that for any other brand this would have probably been a class action lawsuit - or at least an acknowledgement and free fix, but with Apple every time it fails I have to pay out of pocket (it is for development purposes, no I am not a masochist), since the vast majority of Apple users are fine with paying.
