"Date trick" workaround allowed for unapproved apps without jailbreaking.



From Arstechnica:

Apple rules have long prevented emulators for classic game consoles and computers from appearing on the App Store, though some have managed to sneak their way through briefly (or more officially through licensing deal with rights holders). Since last year, though, the makers of emulators like GBA4iOS and SNES emulator SiOS have relied on a loophole called the "Date Trick" to allow these apps (and ROM files) to be downloaded and installed through the built-in Safari browser. The trick gets around restrictions on unsigned apps by setting the device's date back at least two months, allowing users to easily run emulators to their heart's content without jailbreaking.

iOS 8.1 beta testers are reporting those days of easy emulation seem to be coming to an end in the latest update, though. GBA4iOS tester Dario Sepulveda writes that iOS 8.1 Beta 2 blocks the Date Trick workaround, cutting off the ability to install the app.
