DOS emulator for iOS released, runs Windows 3.0.
It's a DOSbox-based disk operating system emulator that runs on iOS. And it apparently does everything that DOS does, including, as you can see in the picture, running Windows 3.0 complete with the Solitaire game.
On the iPhone's retina display, the C:/> prompt is super tiny, but readable. Hopefully we'll be able to upload DOS and Win games to the iPhone now.
