You probably move from Home Screen to Home Screen by scrolling left/right flicking your finger to throw the pages.
There is an alternative approach, which is sometimes more convenient.
The iPhone allows you to create up to nine (9) Home Screens. The small white dots above the Dock Bar shows the number of screens you have, and indicates which Screen you are currently viewing. The image below indicates we are on Screen #2 (yellow arrow points to dot number 2 of 6).
Tapping on one of these dots to the right or left of the current Screen will cause a "page turn" in that direction to the next screen.
If you tapped repeatedly on the rightmost dot, for instance, you can rapidly move Screens to the last Screen.
