To start, when you first turn on your iPhone, if you have any kind of customized html based lock screen you will notice that the image you set from your camera roll doesn’t show up as the lock background anymore, Apple has done away with a usable image that can be called via html and instead renamed that file and the Homescreen background to LockBackground.cpbitmap and HomeBackground.cpbitmap. I tried just putting that filename in to replace in the html and it wouldn’t load. Since most themes don’t use the full resolution image for the lock screen there is still LockBackgroundThumbnail.jpg and HomeBackgroundThumbnail.jpg that are 206×308 and they will still make for a good Neo Style html lock screen.
Moving onto the home screen. The first thing you will notice is, folders, camera, and photos icons have reverted back to the standard Apple icon. Follow the directions below to change the names of these icons in your theme:
Camera Icon
Camera and photos have been separated in 4.2.1
1. Copy your icon-camera.png to a new folder called
/bundles/com.apple.camera
2. Then you will need the icons
•Default.png
•Default@2x.png
•Icon-Camera.png becomes Icon.png
•Icon-Camera@2x.png becomes
Icon@2x.pngPhotos Icon
The Camera was removed from the mobileslideshow but the photos remain.
In /bundles/com.apple.mobileslideshow you need to rename
•Default.png to Default~iphone.png
•Default@2x.png to Default@2x~iphone.png
•icon-Photos.png becomes icon.png
•icon-Photos@2x.png becomes
icon@2x.pngiDevice UI
Folder icon, background image, task switcher icons, dock shadow, multitask shadow, and Rotation Lock
In [/b]/bundles/com.apple.springboard[/b] rename these files
•FolderIconBG.png becomes FolderIconBG~iphone.png
•FolderIconBG@2x.png becomes FolderIconBG@2x~iphone.png
•FolderSwitcherBG.png becomes FolderSwitcherBG~iphone.png
•FolderSwitcherBG@2x.png becomes FolderSwitcherBG@2x~iphone.png
•RotationLockButton.png becomes RotationLockButton~iphone.png
•RotationLockButton@2x.png becomes RotationLockButton@2x~iphone.png
•RotationUnlockButton.png becomes RotationUnlockButton~iphone.png
•[b[RotationUnlockButton@2x.png becomes RotationUnlockButton@2x~iphone.png[/b]
•SwitcherIconShadow.png becomes SwitcherIconShadow~iphone.png
•SwitcherIconShadow@2x.png becomes SwitcherIconShadow@2x~iphone.png
•WallpaperIconDockShadow.png becomes WallpaperIconDockShadow~iphone.png
•WallpaperIconDockShadow@2x.png becomesWallpaperIconDockShadow@2x~iphone.png
Maps Icon
Again Apple has been added to the icon names in
/bundles/com.apple.Maps
•icon.png becomes icon~iphone.png
•icon@2x.png becomes icon@2x~iphone.png
In order to enable your folder wallpaper and switcher graphics there are now 4 files that need to be deleted in
/var/mobile/Library/caches
•com.apple.SpringBoard.folderSwitcherLinen.0
•com.apple.SpringBoard.folderSwitcherLinen.1
•com.apple.SpringBoard.folderSwitcherLinen.2
•com.apple.SpringBoard.folderSwitcherLinen.3
After that respring and you will see the changes.
