Answering the call from users and developers, Apple rolled out bold new changes to it's iOS software, the code that powers the iPhone and the iPad.

Apple's VP of Software Scott Forstall took the stage at roughly 2pm EST in San Francisco to usher in the long awaited features.

The VP said that there were over 200 new features coming to the iPhone and iPad, and took time to demonstrate 10 key ones.

Perhaps  the biggest, and least expected announcement was that the new iOS no longer needs to be connected to a PC for startup the first time or to receive updates. That all happens over the air.

Sustained ovation followed the announcement.

We are living in a post PC world, Forstall says. Especially with the iPad, we are ushering in a post PC world. We know we are selling to a lot of households that just don't have computers.

Now, if you want to cut the cord, you can, he says.

The latest iteration of the iOS will allow iPhone and iPad users to start setting up the device right out of the box, whereas before the device first needed to be connected to  a PC.

The exec also introduced a new notifications feature that makes it easier to see what's happened on the phone in one place.

The way Apple notifies users now is a throw-back to its first iPhone in 2007. Pop-ups appear, sometimes interrupting a user, and forcing users to respond before they disappear. Users have frequently

The notifications are now aggregated and assessable by sliding your finger across the top. Android has a similar feature. When users visit the notification center, they can also see updates on weather and stocks.

An improved email application was also demoed, as well as a unified chat program between all iOS based devices.

The announcement came after Phil Schiller took the stage earlier to usher in new changes to the Mac OS X Lion.

Apple's WWDC will run from June 6 to Jun 10.
