Sony Xperia Z owners are in for some good news, especially so soon after launch: An update for Android 4.2.2 Jelly Bean will be available soon.

For a lot of potential Xperia Z buyers, Sony's decision to go with Jelly Bean 4.1 out of the box instead of the latest version of Android 4.2 was disappointing, but it looks like the Japanese company is prepping an update for a quick release.

According to the Xperia Blog, the Android 4.2.2. Jelly Bean upgrade will be available for Xperia Z some time near the end of March in Europe (and presumably elsewhere). Citing anonymous sources (of course), the site published a leaked image of what is supposedly a screen capture with some firmware details. The Beta version of Jelly Bean 4.2.2 is currently numbered 11.1.A.1.450, but those numerals are expected to change slightly by the time the update rolls out. The firmware update also uses kernel 3.6, which is an improvement over the previous version's 3.4.

Considering the Xperia Z is Sony's new flagship phone, it's probably not too much of a surprise that a Jelly Bean 4.2.2. update would come out so soon. The smartphone just recently became available, and with Sony positioning it as a premium phone, it'll want to make sure the device has all the latest features. That could prove especially useful since the Galaxy S4 launch is right around the corner.

Meanwhile, Xperia J users are in for a treat, too. Their smartphone won't be left behind, as an Android 4.1.2 Jelly Bean update is currently rolling out over the air with a firmware version number of 11.2.A.0.21. If you can't get the upgrade just yet, it might not be available for your location. Still, impatient users can always plug their smartphones into their PC and check for the new software via Sony's Update Service tool.

Jelly Bean 4.1.2 features a number of new additions, including Google Now, new notification options and enhanced operating system performance via Project Butter.
