iOS 8 or later on iPhone 4 I searched a way to upgrade my jailbreak iphone 4 with 7.1.2 iOS to 8 or later iOS, but none of them work (one proposed &quot;solution&quot; is to download ifile and change the name of the iOS; this is a bad joke). On this forum there are similar question, but they are too old for this reason I decided to ask this question.
As of date, there is no official way to upgrade iPhone 4 to any iOS after iOS 7.1.2 and iPhone 4s can't be upgraded to any iOS after iOS 9.3.6
