Shortly after Google pushed a Jelly Bean preview update to I/O attendees, RootzWiki made it available to the public. The update was originally intended for GSM Galaxy Nexus smartphones, however hardworking developers were able to iron out the LTE bugs and make it available to all Galaxy Nexus models.
