Today we have some good news for Samsung Galaxy S III owners, as the Android 4.1 Jelly Bean update has been finalised and is already winging its way to privileged owners in Europe as you read this. An October release was rumoured just a few weeks ago, but Samsung has apparently beaten this target, and multiple sources are now confirming its arrival.

As usual with all Android OS updates though, there’s a catch, as at the moment the update is seeding in Eastern Europe, and will continue to rollout over the coming weeks. This means that if you don’t own a SIM-free S III, then you’ve probably got at least four weeks still to wait.

When it’s ready for your phone, it’ll be available as an over-the-air update, or via the Kies desktop software and according toSamMobile.com, you’ll need a Wi-Fi connection and either a power source or more than 50 % battery power to apply it.

Additionally, Samsung has informed TheVerge that various other phones will also be getting Android 4.1 Jelly Bean soon too. Both the Galaxy S II and the Galaxy Note head up the list, and they’re joined by the Galaxy S Advance, the Galaxy S II LTE, Galaxy Chat, Galaxy Ace 2, Galaxy Beam, Galaxy Ace Plus, Galaxy Mini 2 and the Galaxy S Duos. It’s not only phones either, as the Galaxy Tab 2 7.0, the Tab 7.0 Plus, Tab 2 10.1 and the Galaxy Note 10.1 tablets are also eligible for an update.

Once again, exactly when these will arrive isn’t known, as it’s often down to networks to send the update out, but at least we know they’re all coming.
