The Android 4.1.2 Jelly Bean firmware update has finally started to roll out for T-Mobile Galaxy S2 SGH-T989 users in the United States. The firmware was due for more than a month but the wait is over now. It’s your turn to taste the fresh flavor of Jelly Bean.

The new update is already being pushed via Over-the-Air and the users will be receiving it in phases.
