Google has announced the new version of Android Jelly Bean and will be rolled out to Galaxy Nexus, Nexus S and Motorola Xoom in July. Jelly Bean (or Android 4.1) is not a major release, instead it polishes the features of Ice Cream Sandwich which was released late last year. Along with new features, Jelly Bean also has a pack of new wallpapers available. Google has packed Jelly Bean with a set of 10 new wallpapers. Guys at the DXA Forum has extracted the wallpapers from the SDK which was released yesterday by Google.
So if you want to try those wallpapers on your Android phone, you can download them now.XDA Developers
