iPhone OS 4.0 Will Include iChat

 iPhone OS 4.0 Will Include iChat.

Although Apple CEO Steve Jobs gave the world its first official look at iPhone OS 4.0 this week, he apparently didn't reveal all its features. People combing through the developer version of this OS have found that it will include video conferencing software.
iChat Software...Buried in the next version of Apple's mobile operating system is a process named "iChatAgent", leaving very little room for doubt that this service is coming to Apple's smartphones and similar devices.

iChat is currently available on computers running Mac OS X, and allows users to communicate with instant messages and two-way video.
...and HardwareIf future iPhone, iPod touch, or iPad models are going to offer video conferencing, Apple is to need to build in a front-facing camera, Evidence that this is in the works has also been found.
Those with early access to iPhone OS 4.0 have found code that will allow devices running it to switch between a front-facing and rear-facing camera.
It's likely Steve Jobs didn't bring up this feature at Wednesday's official announcement of this new operating system because doing so would reveal that future models will include a front-facing camera, and Apple wanted its event to be about iPhone OS 4.0, not the hardware running it.
