Aloha everybody,
I've read on here somewhere that 3G data can't be turned off on either iOS 5 or the iPhone 4S. I beg to differ with that. Take a look at the attached screenshot and tell me if what I'm seeing is not what you're seeing. This has been the same for the last couple of software updates, IIRC. I really don't understand, but maybe I misunderstood the original comments. I got there by going to Settings -> General -> Network
