- SpringBoard no longer needs to be modified (via SummerBoard) in order to show extra applications in the /Applications folder.
- All applications now run as the user 'mobile' instead of as root.
- Preferences are now stored in /var/mobile rather than in /var/root.
What does this all mean? I'll tell you what it means. Even though there are no applications available for purchase (besides the iPod Touch's $20 "upgrade package"), the installation architecture appears to be there already. It also appears that the frameworks have undergone many changes, ostensibly to make it easier for official SDK developers to make programs. It does, however, break many of the existing applications including most of Nate True's (Lights Off still works though).Additionally, the SpringBoard app appears to have widget support - it contains a class called SBWidgetApplication which manages the package location and icon.
