I want to disable my cellular carrier temporarily to increase battery life. I already know how to turn off 3G, but I also want to disable incoming phone calls to basically just turn the iPhone into a wifi only device to surf the web for as long as possible without recharging. I suppose I could just remove the sim card, but isn't there a way to achieve what I want through the menu's?

iPhone 4, iOS 4.3.1

Go into settings and turn on airplane mode, then turn on wifi.  That will turn of the cellular radio (voice and data) and leave just wifi active.
