Dev:SBIcon

SBIcon is a class representing an icon displayed by. It is not typically used directly; instead, its various subclasses are used: SBApplicationIcon, SBBookmarkIcon, SBDownloadingIcon, and SBDestinationHole (which is a blank space used when rearranging icons).

In iOS 5 Apple split up SBIcon, creating a separate class for SBIconView, and just leaving SBIcon with behind the scenes stuff.
