An official signed copy of Android 4.1 Jelly Bean has been posted on the web. Sadly, this build is only for the Galaxy Nexuses (Nexi?) given out to Google I/O attendees, which are running the IMM30D firmware.

The download link is below. We wouldn’t expect it to take too long for the developer community to get this build to working on the other Galaxy Nexus devices.

Keep in mind that I/O Galaxy Nexus devices are slated to receive Jelly Bean over-the-air tonight anyway, so this may not be worth the trouble for everyone.
