Tried searching around for answers, but I'm not having much luck. I'm on a 3G, running 3.0 firmware on a windows machine. All I really want is the MMS update in 3.1. I understand there have been issues with battery life with 3.1.2? What should I do, upgrade to 3.1 and blackrain it? If so where should I go to get the 3.1 upgrade? Doing it officially through itunes doesn't seem like an option. Is there a restore file to download? Or am I wrong, and can go ahead and upgrade to 3.1.2 and run blackrain on it?
