If you can’t wait to get some Android 4.1 Jelly Bean action on your favorite Android device, we have a treat for you. Here are the official Android 4.1 Jelly Bean wallpapers which have been extracted from the over the air update for the GSM Galaxy Nexus (takju), the device handed out to developers at Google I/O.
For ease of installation, you can download an unofficial APK, thanks to @kovdev, that has them all included for you. Simply install the Jelly Bean Wallpaper APK as you would any other third party APK. Once installed, launch the application and select your designed wallpaper. You can launch the Jelly Bean Wallpapers by accessing your Wallpapers setting.
For those of you that are rooted, you can also install the Galaxy Nexus Jelly Bean boot animation. Be warned, it isn’t as exciting as the current stock boot animation (see below). Download the official Galaxy Nexus boot animation extracted from the OTA update. Copy the bootanimation.zip file to your SD card. Using Root Explorer or via ADB, move bootanimation.zip to /system/media/bootanimation.zip.
Note: You may wish to first backup or rename your current bootanimation.zip file before proceeding with the above.
