As one of the people who have just updated my hacked iPhone to 1.1.1 (with most of the hacked apps working properly now - we think it is a safe time), I noticed that Apple inexplicably threw us with hacked iPhones/iPods a bone. We no longer need any of the 3rd party launcher applications to get to all of our apps if we've exceeded the 20 that fit on the front page. Apple has built in this functionality.
You won't notice this functionality unless you hack the iPhone and add additional applications. When the number of applications overfills the screen, you are presented with dots above the dock items. If you swipe your finger horizontally like you do when browsing pictures, you will get a new page of desktop items. Very nice Apple.
It is a system wide interface. If you go to the weather application and add more than one city, you will see these dots
