I haven't been in the JB community for awhile but I don't believe iOS 6 has been jailbroken yet. I could be wrong. Either way, it won't take long.
 
I've used it on IOS 5 and 3G Unrestrictor... But to be honest I prefer Skype which works on more devices... Facetime to me is an example of Apple trying to fix something that wasn't broke... and sell more IOS devices. Also , I think (Skype) is free over cellular on A.T.&T. and most likey other carriers as well..
 
Is there anyway to jailbreak iOS6 to allow Facetime over Cellular since AT&T wont allow it?

No, stay with 5.1.1 on your iPhone 4S/4 for now. I'll purchase an iPhone 5 when an untethered Jailbreak is announced for A6 chip.

Remember it took six months for one to be released for the 4S !😕
