This has pretty exciting possibilities for Webinar/virtual classroom applications. The demo this morning was Skype. Until now, if you weren’t running Skype in the foreground on your iPhone, you couldn’t receive calls, and if you left the Skype app during a call, the call would disconnect. Now even when the phone is locked, you will still be able to receive Skype calls. When the phone is asleep or when the user is running other apps, VoIP apps can receive calls. When you send Skype to the background, incoming call invites will appear as the standard iPhone/iPod notification. Clicking the answer button brings the Skype app back. One question in the backchat during the presentation was whether there might be a new iPhone coming with a front-facing camera for such calls, but this went unanswered.
