No, it is not Jelly Bean, or at least not just yet. As Michael Fisher points it out in his editorial as well as the After the Buzz episode dedicated to the phone, Verizon Galaxy Nexus owners are not happy owners when it comes to the Nexus experience and timely Android platform updates.
However, a leak from Verizon’s system is showing an upcoming OTA update for the phone. It is reportedly build IMM76Q and there are so far mixed reports: some believe it is a performance improvement and bug fix update while others consider it to be a very small refresh meant to avoid future possible litigations. Let’s just hope this is the last update before the one everybody is waiting for: Jelly Bean please!
