Σύμφωνα με τις πηγές του BGR, το FaceTime θα μπορεί να λειτουργήσει σε όλα τα iDevices. Απαραίτητη προϋπόθεση θα είναι η ύπαρξη ενός Apple ID με σκοπό να ταυτοποιείται η κλήση με το email του χρήστη:
It’s actually pretty simple… Your Apple ID will be registered with your device/s, and that will allow other Apple devices to start a FaceTime call using your email address. Apple will also reportedly make use of push notifications to deliver these incoming FaceTime connection requests as we have been informed there is a push notification detector tied into the FaceTime frameworks in the new iPhone OS 4.1 beta.
We’re not sure how Apple will handle an iPod touch trying to connect to a FaceTime session on an iPhone as it seems Apple would still require you to use the iPhone’s phone number, at least that’s how it seems currently. In all reality though, we’re pretty confident Apple will make a straight forward and unified way of talking to every eventual FaceTime-enabled Apple device or computer, and it might be an Apple ID, or possibly something else down the road.
