another newbie question, not a repeat of 10 posts of buying an 8gb touch and if it was safe to jailbreak ala linden, but when do the icons become jiggly. only noticed it one time on my touch.
Yeah, this is useful for moving webclips and applications around on your home screen (or indeed home screens)
You can create a new page for apps and web clips by dragging an icon (while wiggling) to the right hand side of the screen.
You can have four or less icons in the dock
Up to 9 pages of homescreens
This is all very well documented, with how-to videos, on Apples website.
