It was recently discovered that AT&T will likely charge for FaceTime over 3G when iOS 6 launches for the public this fall. Users could previously only use Apple’s FaceTime when connected to a WiFi network, but iOS 6 (now in its third developer beta) will allow for FaceTime over both WiFi and a cellular connection.
Sprint, the nation’s third largest carrier, now says that it will not charge its customers for FaceTime over 3G in iOS 6. Both AT&T and Verizon still refuse to give any details.
