For some, even the newly expanded 11 Home Screen, 180 (including 4 fixed dock) app slots under iPhone 3.0 isn’t enough. It’s not about need — it’s about want. Luckily, iPhone 3.0 offers another handy, theoretically unlimited way to access apps: Spotlight. According to David Pogue:

You can install UNLIMITED APPS! Only 180 show up as icons—but Spotlight can find and open all of them! (And yes, we tried. Stopped at 250!)

So, check off every single one of your 56,000 (maybe?!) apps and sync them over. Then, instead of swiping right through 11 pages only to find the excess unaccessible, swipe LEFT to go to the Spotlight Search screen (or just press the home button again to get there super quick).
Next, start typing the name of the app, hidden or otherwise, you want to access, and as soon as it appears in the results, tap it to launch.
Boom. App pack rat bliss.
Note: Spotlight also shows WebClip icons you’ve bookmarked from MobileSafari to your Home Screen, so you can go crazy with quick access to your favorite websites as well.
And for those who prefer not to fill up their iPhone with apps, remember you can delete an app when not using it and download it again via the on-board App Store app, without any duplicate charges, any time. Cloud management is a reality, and a second option.
