Cricket Wireless has today started pushing out the much-anticipated Android 4.3 Jelly Bean over-the-air update to all of its locked carrier-branded Samsung Galaxy S III handsets located in the United States. In addition to the upgraded build of the open source operating system, this update also brings a truckload of bug fixes, stability improvements, speed optimizations, as well as support for Samsung KNOX, Sound & Shoot and the Galaxy Gear.
