I know the 5 column dock works on the Iphone 4, but I can't find an app that changes the rest of the home screen to have 5 columns? I use to have it on my 3gs and loved it. I sit out yet? What should I be searching for in Cydia?
Iconoclasm works mostly great for the iPhone 4. There are a few problems.
First, you can't set up page specific page layouts like you could in older versions. Next, folders will display a black screen if you try to put more icons in them than your layouts allow. For example, if you have a 2x2 layout, you can't put more than 4 icons in your folders without getting a black screen.
