The firmware update bears the 11.2.A.0.21 build number and updates the baseband as well. Naturally, Xperia J users will finally get a taste of Project Butter and the numerous features that Jelly Bean has on tap. The Xperia J is the latest Sony smartphone to get the update keeping up with the Xperia T, TL and V.
As per tradition, the Android update should hit the Xpera J's in an over-the-air fashion. However, in case it doesn't, just hook the phone to the PC Companion and check the update's availability there.
So, with the Xperia J checkbox marked, who's next in line for an update? It seems that the Xperia TX is due to taste those jelly beans in the weeks to come, but nothing is confirmed just yet, so stay tuned.
