One of my favorite ICS ROMs, F1 Galaxy Nexus for i9100, is now available for your AT&T Galaxy S2 SGH-i777. And no, this isn’t simply hellraised but will give you that “pure” Google Galaxy Nexus experience you’ve been after. There’s no preservatives or any other extras added so if you want to enjoy pure stock Galaxy Nexus experience on your AT&T Galaxy S2, give this ROM a go, I think you will like it and let me know what you think of this ROM!!!
To install, install ROM then Gapps! If you don’t install Gapps you won’t get Play Store!!!
