Months after its flighty sibling, the Galaxy S II Skyrocket, received an update to Android 4.1.2, it seems that the vanilla GS2 on AT&T is finally ready for its Jelly Bean bump. Threads on XDA and the official AT&T forums confirm that the update - build number UCMD8 - is now available, just check for an update through Kies.

We don't yet have a changelog for the update, but you can assume that for Galaxy S II users, the number of changes coming from the Ice Cream Sandwich TouchWiz builds won't be huge. You will, though, get some of Jelly Bean's useful additions - rich, expandable notifications and Google Now probably being the most noticeable enhancements.

If you still have an AT&T Galaxy S II (hey, it's getting pretty old), fire up Kies and get downloading. When (and if) AT&T officially announces the OTA, which it likely will at some point this week, we'll update this post with any new information.

    My dad got this phone twelve months ago. Because of the AT&T upgrade changes, he gets to hang on to it for another twelve months. Better late than never is right: for my Atrix 2 it's "never".

    Can this be updated without a PC?

    • Michael Ta

      I think you can. Well, HTC and Nexus can, i don't know about samsung. For htc you'll need 80% battery life minimum and around 1gb free space.

      Apparently at the moment, it requires using Kies (a PC program). I believe when they say that OTA (Over The Air) should be coming soon, that is when it can be done without connecting to a PC.

        OK... Was hoping keis mobile was an option

    I think I'll stay on CM....

    Is there any word on the super brick getting fixed in their kernel? Or am I behind the times on that?

      i was able to upgrade my ATT Samsng Galaxy S2. unfortunately it seems like it unrooted now. I have rooted mine only recently with some struggle, have to root it all over again

        I updated to jellybean via ODIN. I lost root when it was all done and updated. Now I am in the same boat as you. I need to reroot, but haven't found anything on how to do it under the new jellybean.

        • Mac

          I rooted with Framaroot. It a simple one click apk you can download. Just search for it. If I remember correctly, you can get it from xda.

    while us SG3 users are still waiting on 4.1.2 from ATT. WTF

  • Brian Farmer

    The way AT&T has conveniently eliminated the ability to change the notification area is just awful. The dropdown is WAY too crowded now with needless additions.

  • Jezer Garcia

    I so loved this update, it turns my sick gingerbread to a very smooth jellybean But there are some concerns like, there are some times that it randomly freezes and juices out the battery faster. But all in all, this is great! One more thing, how can I root it? Thanks!
