One new feature that iOS 6 brings to the table is FaceTime calling over 3G. The fact that it runs on a cellular network puts carriers in the position of potentially regulating the video calling app. Unlike AT&T which is on the fence, Sprint has confirmed it will not charge for access to the service, according to Electronista. A spokesperson said Sprint remains "committed to our unlimited data, and that means not charging for data consumption based on the application." Verizon Wireless, the third major carrier in the US to sell the iPhone, has not publicly commented.
