iPhone OS 4 is now iOS 4, coming June 21

As part of the iPhone 4 introduction today at WWDC 2010, Apple's Steve Jobs announced a name change for the operating system that powers an increasing number of their mobile devices -- goodbye iPhone OS, hello iOS. And it's coming June 21.

Base features are what we saw at the sneak peak event -- and have detailed in way too much detail already in our walkthrough -- except for the FaceTime (i.e. video chat/calling) feature.

GDGT says cisco owns that trademark, much like they owned iPhone in 2007. It looks a bit weird to me still, and I'm fairly sure the iMac isn't running it, so it will take some getting used to. For Apple to use iPhone 4 for the phone name, however, they needed something more distinct for the OS.
