2G/3G/4G Toggle

[k1fox]

In Android, is there any app that allows you to easily toggle between Edge (2G) and 3G/4G. Everyone that I have tried takes me to the mobile network setting menu as a shortcut instead of actually doing it instantly. Would like to save battery by staying on 2G but switching to 3G when I'm actually going to do something.
