This is pretty cool, I have to say… useless though. There is no on-screen keyboard and no way to hook up an external keyboard via USB either, so at this point it’s nothing more than something kind of cool that you’ll use maybe once then promptly uninstall.
The app is available for jailbroken iPhones only obviously, and it’s available through Cydia. It’s called “Windoze” so search for that… It’s in the xSellize repository, or you can install the .deb package manually through the terminal if you so choose.
