This is disappointing beyond words, and feels like their take on MMS all over again. Why Apple did not choose to implement standard 3GPP video calling is utterly beyond me (even if the quality per bit might be better, there have been phones doing this since 2004, and any dirt-cheap Nokia will place video calls to any other 3G phone on the planet). Besides, doing it over IP is much more taxing on mobile networks and is likely to have worse QoS overall, since 3GPP video calling reserves a circuit-switched, end-to-end 64kbps call with guaranteed QoS, instead of trying to allocate a bulk packet radio bearer at 7.2Mbps - which is what will happen if this goes over mobile networks in the raw. That’s the reason we in the mobile industry call it “a standard”, you know?
