Itching to get the latest Android 4.2.2 Jelly Bean update on your Samsung Galaxy S III? Well today could be your lucky day. A pre-release version of the software has been leaked online, allowing Galaxy S III owners to get the latest Jelly Bean features in advance of Samsung’s official release.

The software comes with a long list of new features — some of which are currently only available on the Galaxy S4 (officially) — plus some user interface tweaks and other improvements.

Samsung CEO JK Shin expects the Samsung Galaxy S4 to surpass 10 million sales next week, less than a month after its debut. The milestone will make the new device the fastest-selling Samsung smartphone to date, a title that’s currently held by its predecessor, the Galaxy S III.

As successor to the hugely successful Galaxy S III, the Galaxy S4 always had big boots to fill — but it appears to be doing that with ease. In just four days last month, Samsung shipped a staggering 4 million Galaxy S4 handsets. It’s now on track to ship 10 million by the end of May.

Apple has confirmed it will seek to add Samsung’s new Galaxy S4 to its ongoing patent-infringement lawsuit against the Korean electronics giant.

In a statement filed in the U.S. District Court in California on Monday, Apple said it has analyzed the Galaxy S4 and “concluded that it is an infringing device and accordingly intends to move for leave to add the Galaxy S4 as an infringing product.”

Samsung Galaxy S III users on T-Mobile USA can look forward to a new Android 4.1.2 Jelly Bean update today, which introduces a whole host of new features and improvements, including Multi-Window and new apps.
