How to move apps anywhere on the screen of an Iphone or Ipod Touch?

I have an Iphone 3GS and I'm trying to find out how to move the apps anywhere on the screen. I know you can work your way down the screen in a row but I wanna know how to do it in columns. My friend did it in a column and I wanna know how. I can't find anything about it on the internet, does it even work? Or is it a jailbroken phone?

To move them anywhere on the screen you will need cydia (jailbreak)

Hope this helps!
