Apple introduced iPhone OS 4.0 on Thursday, complete with a beta version of the operating system for developers, and within hours a video showing off an iPhone 3GS running the beta software made its way to YouTube. The video was posted by Makowe ABC and shows off upcoming features such as multi-tasking and app folder groups.

The narration in the video isn’t English, but notes in English have been added to help make it clear how each feature works.
