TUAW was slipped a screenshot today showing something called iChatAgent running on iPhone 4.0. iChat is Apple's instant message client for Mac OS X that includes voice and video chat, among other features. Rumors of a Mobile iChat for iPhone that would include webcam-style video chat date back to 2008, and were most recently seen in (and then taken away from) iPhone 3.2 for iPad.

Will we finally see an honest-to-Jobs Mobile iChat video this summer at WWDC along with a next-generation iPhone (don't call it the iPhone 4G!) featuring a front-facing camera?

We're not getting out hopes up anymore. Really. We swear...
