I tried flashing one of the cornerstone builds the other day and was quite impressed...until I tried restoring apps and rebooted and the launcher kept FC'g. And the wi-fi would sometimes work and sometimes not and even when it appeared to be working, the browser wouldn't connect to any sites I tried. So, for now, I flashed back to Revolver 4. It would be nice if cornerstone could be a separately installed app for any Android device because it was neat and seemed to have some usefulness.
