iOS 4.2.1 it can only be installed on an extremely limited number of iPhone terminals at the moment, but today we see a video clip in which it works on a Apple Watch, the achievement being truly impressive.
An emulator was used to run iOS 4.2.1 on the smart watch of those from Cupertino and probably this is where the lag in the activation of various functions comes from, Apple Watch having hardware similar to that of the iPhone 4S, so perfectly capable of running this version of iOS without problems.
The idea of seeing the interface iOS 4.2.1 for iPhone on such a small screen and the manipulation of its elements seems very comical, but the hacker who managed to install the operating system on the watch must be praised for such an important achievement, difficult for many people to achieve.
I don't know if we will ever see another version of iOS installed on Apple Watch, but maybe a more powerful hardware implemented by Apple will motivate other hackers to test newer versions of the operating system on the smart watch.
