Nope. Like keeping the phone the way Apple intended it to be. Nets me the best battery life and performance too.
There is a jailbreak tweak called SBSettings that helps with battery life. It gives you one spot to manage all of your devices settings. I can turn Bluetooth on and off with 2 swipes, same with wifi, 3G etc; also you can remove all of your background apps with 2 swipes which helps majorly with battery life.
