So I previously had the leak the installed on a rooted Razr. After an insurance replacement I stayed on ICS and forgot how laggy the ICS update was. This morning I got OTA JB update by checking for updates. THIS THING IS FLYING AGAIN! Much happier with the performance. Battery life seems better, but I'll need more time to assess. I forgot how cool Google Now was for telling me how long to expect my commute to and from work would take (with traffic etc). Overall, so far, after 4 hours, this is a very positive update. Anyone else?
