I had a strange upgrade issue with my unlocked 680. I ran the upgrade
file on my PC and it coughed up an error saying that it couldn't find a
particular java file. In used the SD installer instead and that worked
like a champ. One restore later and everything was back where it
belonged. So far I haven't noticed any huge difference in battery life,
but I've been at my desk all day so it has been on and off the charger.
I'll know more in a couple days.
