What is the general consensus amongst you. Should I update the 4.2 to 4.3 or not worry about it. Usually updates ruin things historically. Has anyone done it and reverted back to 4.2? My only gripe is 3G and am guessing that's the network not the phone. 4.2 has been OK for me. But did update improve day to day stuff, Emails, Safari, etc.
