Thanks to a number of tipsters who’ve contacted us, it appears that both Optus and Vodafone are rolling out the Android 4.1.2 Jelly Bean update to their handsets now. From what I can tell the update is going out as an OTA update but can also be upgraded via Kies as well if you so wish. To prompt your phone to upgrade simply go to Settings > About Phone > Software Update > Check now for update.
The update is for the Optus GT-i9300 and GT-i9305, the Vodafone handset is I believe the i9300 but please correct me if I’m wrong. The Telstra update is listed on their Crowd Support forum as being Approved and the status is “Scheduled to begin staged deployment at 2:00 PM AEDT 4th February” however comments suggest this may be the GT-i9300 only not the 4G GT-i9300 model, if you have a Telstra Galaxy S III with Telstra please advise if you’ve received the update and on which model.
The Android 4.1.2 upgrade brings the Premium Suite and Samsung has provided two videos on the Android 4.1.2 Premium Suite for you to have a look at : Part 1 :
