For more than a year iOS had a bug that allowed anyone to change the date of the operating system to install game emulators, of almost any type, without doing jailbreak own terminal. The bug was based on changing the date to be able to install an expired developer certificate which still allowed the installation of some game emulators without having jailbreak, but Apple has blocked this functionality.
It looks like in iOS 8.1 the bug no longer exists and changing the date to a date earlier than the one we are in still does not allow the installation of the expired certificate required for using game emulators. No one knows if the change is permanent or will be removed until now official releases of iOS 8.1But Apple Lossless Audio CODEC (ALAC), you will disappoint many iDevice owners with this update and probably many will avoid installing it.
The release of iOS 8.1 could take place on October 20, and until then you can find out in this article how can one be installed game emulator without jailbreak.
