It has already been released by Sprint and Verizon, and now AT&T is finally bringing the Android 4.3 Jelly Bean update to customers with a Samsung Galaxy S4. In addition to support for Galaxy Gear, the 718MB release adds the new KNOX security features, as well as TouchWiz improvements and other new features.

The Samsung Galaxy S III’s Android 4.3 Jelly Bean update, which first started reaching international handsets on November 4, is now rolling out in the United Kingdom. It will reach unlocked and unbranded handsets first, and users will be able to download and install it over-the-air or via Samsung’s KIES app for Mac and PC.

After Android 4.3 Jelly Bean arrived on the Galaxy S III last month, Galaxy Note II users have been eagerly anticipating an update of their own. And although it hasn’t quite made its way into consumer hands yet, it looks like it is close, with Samsung service centers now getting the release.

U.S. Cellular is the latest carrier to be rolling out the much-anticipated over-the-air updated OS version to all its Galaxy S4 carrier-branded smartphones. This hefty upgrade, which weighs in at 537MB, brings the latest build of Android 4.3 Jelly Bean together with support for the Galaxy Gear.

Samsung has today begun rolling out its Android 4.3 Jelly Bean update to the international Galaxy S III (GT-I9300), just weeks after the update was made available to Galaxy S4 owners. The release brings a whole host of new features and improvements, including Galaxy Gear support, the ability to move apps to the SD card, and lots of user interface updates.
