    I get really bad reception where I live, so the new iPhone with WiFi Facetime will allow me to make calls without using an App, hopefully without calling only Iphone people. But my question is will people be able to call me in my "bad reception" with or with out Facetime? Not that it changes my purchases, just want incoming calls to run off WiFi outside of Apps.

    I think the voice portion goes over 3G and the video over WiFi.

    Not voice only calls...and not to non-iPhone 4 owners. Voip would work for though.

    No way does the voice of the call split off and go to cell towers while the video goes to WiFi. DO you realize what kind of sync issues that would cause???

    Apple is making Facetime an open standard so that other developers can use the tech. I'm sure you'll see it on Skype in the near future.

    It uses H.264 for video, AAC for audio and SIP – IETF for VoIP. Esentially it's a VoIP connection with video streaming.

    At the iPhone hacks section.
    It all goes thru wifi/voip connection. Both audio and video.
    It doesnt use 3G/edge/gprs
