New iChatAgent Process in iPhone OS 4.0 Suggests Video Chat

Developers have discovered a new iChatAgent process running as part of the iPhone OS 4.0 beta firmware.

According to TUAW, It seems unlikely that Apple would merely introduce an instant messaging app without support for video conferencing. Although a front-facing camera on the iPhone has been rumored from time to time and it's one of the most requested hardware features for the iPhone, battery drain during video conferencing is always a concern on a mobile device.

This is the best hint thus far of video chat on the next iPhone. You can see the agent running in the screenshots below...
