For a couple of days I enjoy iOS7 beta version.
Besides a lot of new functionalities, today I realized a new FaceTime option which is not mentioned so much.
As its visible at the screen shot that I had attached to my post, in iOS7 FaceTime will be available not only for video call but also for audio call.
This is good news for iOS users especially who makes international calls often.
However, on the other hand it’s an indicator that voice call revenue for GSM operators will have one more negative impact in close future.
Lets wait to see what additional new functionalities may take place in public version of iOS7.
