Itching for some Android 4.1 Jelly Bean action? Here’s your chance: site RootzWiki has made Android 4.1 Jelly Bean preview update that was meant for Google I/O attendees available for Galaxy Nexus owners ’round the world. Initially RootzWiki was only able to make the update work for GSM owners of the Galaxy Nexus, but has gone on to make it available for all versions of the Galaxy Nexus. You can go directly to RootzWiki and download the update, but don’t come crying to us if something goes wrong and it bricks your phone. Don’t say we didn’t warn you.
