DOS probably isn’t what will have millions of people rushing to buy Apple’s iPad, but that doesn’t mean that it isn’t welcome on iOS. Software developer Fast Intelligence somehow managed to get iDOS approved for Apple’s App Store, allowing users to run the emulator that supports DOS and Windows 3.0 on iOS devices. Of course, the freedom was short-lived as the $0.99 app was promptly pulled from the store. Of course, if you do have a jailbroken iOS device you can still pick up the app from the Cydia store.
