While the shatter-proof water-proof Sony Experia Z is in wait for its official Android 4.2.2 Jellybean upgrade, it seems that the same firmware has leaked through web. A forum member of XDAdevelopers posted a thread with attachments to developer version of Android 4.2.2 for the Xperia Z (C6602/C6603). According to him, the software is only for uncloaked boot loaders and it is not official.
