http://freedownloadbuzz.org - I still remember when I bought my first ever Samsung Galaxy S II GT-I9100. It was with Android 2.3 Gingerbread and later I was able to upgrade it to Android 4.0 Ice Cream Sandwich. It’s almost been 9 months since then. Well, Android 4.1 Jelly Bean is the latest OS that everyone is talking about and why shouldn’t I get my hands on it? But there is no official update for it. So what? it is all possible through custom ROM for the Galaxy S II which is ReVolt JB ROM developed by XDA developers member johnhany97.
