"Bandwidth in 4G LTE networks initially is not going to be a problem, but over time, if you use it for interactive video or watching moves, yeah, it's going to be a problem," Hourihan said.
A common complaint with FaceTime even over Wi-Fi has been video freeze-ups and dropped calls that make the experience difficult. If LTE isn't available at the tower near a FaceTime user, 3G networks might offer a worse experience than Wi-Fi. //computerworld.com
