Are you tired of using your iPhone to do all kinds of iPhone stuff?

lets you install and run Windows XP on an iPhone 7 without jailbreaking the device.

The technique involves side-loading an app through Xcode and then running an emulator to pull up Windows. you’ll need to be able to write C or C++ and generally be willing screw with code. Even then, you won’t be able to do much in the operating system, because emulators gobble up a lot of processing power. Still, it’s a fun party trick, assuming you go to really nerdy parties.
