My understanding is that it won't clear ANYTHING. The applications will simply not show up on your homepage. They'll still be there taking up space though.

Interesting Point of View. With those "Spaces" Apps where it allows you to make blank spaces on your home screen, when you tap in the area of one of them, the Apple "A" sign for Application comes up. I think the firmwares update all of the system files and adds what was needed to be added in that firmware.
