As of this morning, there are reports that some users of the LTE Galaxy Nexus are receiving an OTA update of their phones from Ice Cream Sandwich (Android 4.0) to Jelly Bean (Android 4.1.1), labeled as version JRO03O. If you are one of the (likely) very few non-rooted, non-custom ROM users, this may be significant news to you. With the addition of Google NOW, and a host of speed and smoothness enhancements, Jelly Bean is the best version of Android yet.
So if you’re stock, keep checking that “system update” button. If you aren’t stock, and want to see what all the fuss is about….well, you’ll have to flash back to stock ICS, and then wait for the update from there to get the goods. If you’re like me (rooted and custom ROM) you’ll probably just yawn and move along. So there you go!
