Don’t want to lose your ClockworkMod Recovery or don’t want to re-root your phone after updating to the official AT&T ICS for your Galaxy S2 SGH-i777?
No worries, just flash the CWM-zippable UCLE5 ICS official update with root. (Or you can unroot to ICS.)
This one comes with a custom kernel so you should be safe btw.
