Install more than 180 apps on the iPhone/iPod touch

The latest version of the iPhone OS allows you to have 11 pages of 16 icons, plus the four permanent icons at the bottom of the screen, for a total of 180 apps. You can actually have more than 180, though only 180 icons will be visible.

To get to the invisible apps, just do a search (press Home from the home screen), and type part of the non-visible app’s name. I don’t know how many of these invisible apps you can have, as I have not tried more than three so far.
