Just as hope started to fade away, AT&T users of the original Samsung Galaxy S2 (model number SGH-I777) are being treated to the much awaited and oft-delayed Android 4.1 Jelly Bean upgrade.

Samsung Galaxy S2 ATT AT&T Samsung Galaxy S2 (SGH I777) finally gets Android 4.1 Jelly Bean update

The news comes a good couple of months after AT&T has begun rolling out JB updates for the Galaxy S2 Skyrocket. Meanwhile, essentially all “international” GS2 versions have been bumped up to Android 4.1 during this past spring, so you can say the circle is finally closing.

The SGH-I777, unlike the S2 Skyrocket (aka SGH-I727), packs a dual-core 1.2 GHz Exynos processor under its hood and sports a 4.3-inch 800 x 480 pix res Super AMOLED screen. The now mid-ranger was the cream of the crop in October 2011, when it first saw daylight, running Android 2.3 Gingerbread out the box.

Swiftly updated to 4.0 Ice Cream Sandwich in June 2012, the AT&T S2 was subsequently left to dust for unknown reasons. Thankfully, the phone’s updating saga now comes to a very happy ending, as there are very slim chances Android 4.2, 4.3 or 5.0 will ever be rolled out.

Still, you have no reason to be pissed… anymore. After all, Android 4.1.2 comes with numerous treats and goodies in tow, including Google Now integration, Project Butter performance enhancements and oodles of bug fixes.

The reported build number of the update is UCMD8, but for the time being we don’t have an official changelog and we also don’t know exactly how much the software pack “weighs”. You should keep in mind that you can only upgrade your S2 via KIES as of yet, though an OTA (over-the-air) launch is likely slated for the near future.

Now let’s hear it from you AT&T GS2 users out there. Have you received the Android 4.1 bump? Is everything exactly as you expected? Any bugs to report? Unexpected tweaks? Noticeable speed enhancements? We’re all ears.
