Today Apple is announcing iPhone OS 4.0 software to devlopers. This is a brand new version of Apple’s iPhone operating system, and is expected to have loads of new features that will make the iPhone a much better smartphone.

You can now watch the live keynote here.

Some features that are expected to be announced during this live event include:

• Multi-tasking
• Flash support (doubtful about this one as Jobs doesn’t like Flash at all!)
