So just to be clear, if I am traveling outside of the country and don't want to have any data charges on my iphone 4s, should I turn off data roaming or cellular data or both? What is the difference between these two options?
iPhone 4S, iOS 5.1
Switch Data roaming off, when outside your country.
Cellular data off: means that all data like e-mail, safari and push notifications are transferred only via wi-fi and not through a cellular network. This is valid for your country and within your home cellular network
Data roaming off: Similar to above, but outside your home country, i.e. in foreign countries. So there are no charges for using of Safari, Mail, MMS or other data services, simply because it is not possible to use these apps.

Turn both off. I took lots of photos outside of the wi fi network I was connected to and got hit with a wopper of a bill because of data roaming. Turn both off at the airport before leaving American airspace.😀 I still have both turned off.
