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.
