My phone is on at&t. I decided to ask LG themselves and this was their reply. Not sure what they would say fro the sprint side.
Steven, no word has been received yet when we should even expect the OS Jellybean Update.
I would simply continue checking periodically with us until we can tell you for sure when to expect it.
We are available by email or toll free 24/7 at 1-800-243-0000.
Thank you and be blessed, Steven!
Don't need jellybean. The LG Optimus needs a patch to fix some bugs. But, an OS update is not needed. Its like saying, the original EVO would be better with an ICS update. It wouldn't. Matter of fact it would either run like crap or Sense would have to be removed. Now that's not the case with the Optimus but, jellybean is not going to make the this ...less than one month old phone seem...NEW??
There's more than meet the eye with this phone. Play with the options.
If nothing else, Jelly Bean would add Google Now. That alone would make this phone like "new".
Absolutely agree,have been using Nexus 7 with 4.2.1 overclocked,the LGOG is lot faster and I'm really enjoyed LG UI with all the extras,do not miss JB at allMeh had jelly bean on the s3 and traded it for this the phone is fast as heck now I really don't think project butter will be very noticeable but I want the notifications that's it. Google now is cool but not all that
Edit
Let me clarify what I was trying to say Google now is a great feature to have but we already have 95 percent of the functionality of 4.1-2 so I see no reason to go crazy waiting over an update. Enjoy your phones live your lives and before you know it you will get an update notification that jellybean is ready for your phone and the whole waiting process can start all over because Google will have 4.3 or whatever their going to number it out. And if you bought this phone with hopes for a quick release if jellybean I think you bought the wrong phone. But if you bought this phone because of the insanely food screen its fast as heck and just plain awesome then what do you have to complain about
