Elements

The images of the notification center begin with "BulletinList". They are a lot but the most interesting are the following:

"BulletinListLinen.png" ("BulletinListLinen~ipad.png"): it's the background of the notification center. Its size is 480x480 px (480x1024 px).

NOTE: it's needed to delete a file called "com.apple.SpringBoard.notificationCenterLinen", that is in the path var/mobile/Library/Caches, to make the background change takes effect. After that do a respring.

"BulletinListGrabber.png": it's the small rectangle that appears at the end of the notification center. Its size is 45x17 px.

"BulletinListTab.png": it's is the background that appears when the BulletinListGrabber is shown in a fullscreen application. Its size is 47x21 px.

Note: the rest of the images can be found in the downloadable file "SpringBoard".
