This Android 4.1 has been made available only via LG Update tool, so you will have to download it from their support site and it works only with Windows. There is no word on when LG (if ever) plans to release it over-the-air.
The update brings the usual Jelly Bean goodness like Project Butter improvements, UI enhancements, better notifications, Google Now, offline-voice typing and more.
There is no official word on when the update will reach India, but considering that it is already available for unlocked units in Europe, we can expect to see it in the coming weeks.
LG Optimus 4X HD was originally announced at Mobile World Congress last year and come pre-loaded with Ice Cream Sandwich, Jelly Bean will be its first major Android update.
