In a tweet that has just gone out, Optus has advised that owners of one of 2011’s most popular phones the Samsung Galaxy S 2 will begin seeing their Jelly Bean update over the next week. This update will take the Galaxy S 2 from Android 4.0.4 to Android 4.1.2 and should come as an OTA update, but for those who cannot wait for the OTA notification you can always try downloading Kies.
Samsung Galaxy S2 customers: Jelly Bean rolls out over the next week starting today! Look out for the notification or check via device/Kies!
