With my loved ones long away from me, I have missed the ability to use my iPhone’s FaceTime over 3G a few times. Even if the quality would have been bad. Well, it seems that Apple may be testing it or getting ready for it, according to this screenshot.
The error appears in iOS 5.1.1 when turning off 3G, according to Romanian Apple blog iDevice.
But while Apple may be testing it, the question is if carriers would allow it and how. Or if this even makes sense in the United States, given the impending death of unlimited data plans. [iDevice]
