I like my iPhone springboard to be completely empty.
I have done this previously by making all the icons invisible with costumize.
And I launch my apps using the dock app from the installer.

The dock app is great, but I want something nicer.
So I know that when you have like 15 icons, you can switch between the 2 screens of icons.
I want to be able to do that, but have like 3 screens.
so it would look like this:
screen 1: icons
screen 2: icons
screen 3: empty

you know what I mean?
