Samsung started to roll an update to the operating system of Galaxy S3 phones (I just got mine).
Android Jelly Bean is being pushed over the air or via the Samsung Kies software, first to unlocked Samsung Galaxy S3 phones.
Network operators Three, O2 and Vodafone previously made the OS available to their customers, leaving Orange and T-Mobile as the only major providers yet to offer it.
Samsung initiated a gradual roll out of the operating system in Europe last month.
In the US market Sprint is the first U.S. carrier to update the Samsung Galaxy S3 to Android 4.1 Jelly Bean. To date, Verizon, AT&T, T-Mobile and U.S. Cellular are still waiting for their turn.
