After it began rolling out on certain British carriers last week, the Android 4.1 Jelly Bean update for the Samsung Galaxy S3 has this morning started to hit unlocked handsets. Those whose phones are parts of the "BTU" (British unlocked) region can now grab the 284MB update over-the-air or through Kies.
In addition to bumping Samsung's flagship smartphone up to the latest version of Android, this software update also adds a number of new features to TouchWiz. These include "blocking mode" for better control over notifications, alerts and callers, and an optional new "easy mode" for the home screen launcher, which automatically populates it with useful widgets. And, as it's Android 4.1, you get features like the new Google Search app with Google Now, and performance enhancements thanks to Google's "Project Butter."
