I want to Facetime a friend who is currently working abroad. I have an iPhone 4 and have WiFi access. Will the phone automatically use the WiFi? How do I make sure that it doesn't use 3G?
The iPhone 4 can only use FaceTime over WiFi. Only the 4S and the 5 can use it on 3G/4G LTE.
Thank you very much, Meg. That's extremely helpful - and reassuring!!
