Jelly Bean Hidden Feature: Multiple User Support

There's a hidden feature in Jelly Bean, only accessible if you run a custom ROM with it enabled: multiple user support. This lets you control access to your phone by another person. They only see the apps you want them to see, and they can't change the settings. This is perfect for letting your friend use your phone.

This particular ROM is called Domination. It's a CM10-based Android 4.1.1 Jelly Bean ROM that can be found here: http://forum.xda-developers.com/showthread.php?t=1799375
