Emulators for smartphone OS?

[va!n]

In about two weeks i teach a small group of senior citizens and giving an instruction course for smartphone OS (Windows Phone, Android, iOS). Are there any good WindowsPhone / Android / iOS emulators for Windows to show the OS via beamer on a big wall?

To the best of my knowledge there are no ios emulators for windows.

Android you can use something like Geanymotion which allows you to set up emulation of phone or tablets and works reasonably well, it does require an account but is free, the account just gives access to downloads for different emulator setups like samsung galaxy phones or tablets etc.

I have no idea about windows phone emulation but having used my dads win8 phone its pretty much like windows 8 tiles.
