Warnings hint at 3G video support
The latest iPhone 4 SDK beta appears to include new code related to video conferencing functionality. Although basic video conferencing provisions have been included in the past firmware releases, the latest offering expands a number of status and error strings.
One of the new messages, posted by MacRumors, hints at a registration requirement, alerting users if the "device has not been registered for video conferencing." The list of new strings also indicates the service will be integrated into the Game Center, allowing users to join video calls with other gamers.
The list of error messages has been modified, with new messages related to Wi-Fi connectivity but no references to 3G or cellular connections. It is unclear if this is an indication that Apple will allow video conferencing to be used on cellular networks.
Video conferencing is widely expected with the next iPhone, as the leaked prototype clearly integrated a front-facing camera. Apple has yet to officially confirm any of the specs, however.
