We have reported that Samsung Galaxy S II won’t get official ICS update by Samsung. Now, an unofficial Android 4.1 Jelly Bean ROM is available for Galaxy S II GT-I9100 smartphone.
The custom ROM revealed on a post at XDA-Developers forum, based on Jelly Bean for Galaxy Nexus. People who attended Google I/O event at the first day got a Samsung Galaxy Nexus with Android 4.1 Jelly Bean besides Google Nexus 7 Tablet and Google Nexus Q media player. The custom ROM uses modified kernel based on CyanogenMod 9.
Unfortunately, the ROM still has many bugs, including Wi-Fi, Bluetooth, Google Search, camera, and SuperUser access. For Galaxy S II owners who want to install that custom ROM, you can read the details here.
