The Upper Limit on Third-Party iPhone Apps: Five

Side note by Dan Moren in his write-up on Nullriver’s iPhone installer app:

One interesting note: if you install more applications than fit on the iPhone’s home screen (five, including the installer), your apps will scroll off the screen and you won’t be able to access them.

In other words, Springboard, the app that presents the iPhone home screen, doesn’t support scrolling if you install more apps than fit in the remaining four icon slots.
