Check out this ICS ROM for AT&T Galaxy S2 SGH-i777! A CM9 port, this ICS ROM is pretty complete except for minor things like the back button and search button not working. Other quicks include the screen turning off and on randomly during its sleep state but if that doesn’t bother you, you can get “almost” full ICS experience on your AT&T Galaxy S2 with Face Unlock working too. Other than those small issues, everything works including data/wifi/bluetooth/camera.
I know you’ve all been waiting for this so go ahead, download this ROM and try it out yourself, very-usable ICS ROM. And yes, it will only get better and better from this point on.
