Apple iOS 6 comes loaded with one major enhancement related to the Apple FaceTime video messaging service.
Apple iPhones would finally get the ability to start FaceTime conversations on mobile networks.
Apple has until now restricted FaceTime to Wi-Fi internet connections only.
Online sources report that testers of iOS 6 are currently facing restrictions on AT&T network when they try to use FaceTime on their mobile networks.
Experts believe that this could be an indication that AT&T would charge for FaceTime service on their network.
AT&T has not exactly denied these speculations. The company said that they would update the messages shown to consumers when iOS 6 is released later this year.
