Android 4.1 JellyBean firmware upgrade for Samsung GALAXY S III begun rolling out for about a month and a half starting in Eastern Europe (Poland) and spreading gradually from there world-wide.
Today the latest version of Android operating system reached Hong Kong and Taiwan. Users who own a GT-I9300 can get the software update through OTA (over the air) notification upgrade or by simply plugin-in the handset via USB cable to a laptop/PC. Make sure the latest version of Samsung Kies software tool is installed first. Big Thanks to all who sent this in!!!
