Help manually install apps

[gocats7]

I have read that to install apps manually I need to go to menu-applications and check unknown sources. I dont see that as an option in JH7 so am I missing something?

Also, just to review. I can get any APK that will work on my phone, copy it over, double click on it and thats it?
