Does FaceTime on iPhone 4s need wi-fi?

I can't get it to work:/ I don't have wi-fi at home so I'm thinking maybe that's why? But when I try using wi-fi from fast food restaurants it asks for password and it frustrates me cause i don't know:/ lol ahh.

Currently iphone needs Wi-Fi to facetime. It's probably the fastfood restaurant's Wi-Fi that was the problem when you try to facetime there.

October is when they start using 4G for facetime… And being asss holes that they are, AT&T will probably charge you for facetime.

If you jailbreak your iPhone you can get tweaks that let you use your data to use facetime
