Earlier this week, Apple released a beta version of it’s next iteration mobile operating system to developers. iOS 4.3 beta, which is not yet released to the public, incorporates a host of interface refinements and new multi-touch -gesture controls. As for a public release date, Apple isn’t saying, however it should be sometime quite soon as there is never much of a gap between beta releases and public releases of iOS.

The iPad will benefit from several new multi-touch gestures to control various aspects of the tablet. For instance, swiping up with four fingers across the tablet’s surface will cause the multi-tasking drawer to appear. Want to switch between apps? Swipe left or right while working with your current app, and the iPad will move seamlessly between apps that are currently running in the drawer. Want to return to the home screen? Pinch inwards with four or five fingers and you’re there.

Speculation as to if Apple CEO Steve Jobs would make the keynote address at this year’s Apple Worldwide Developer Conference in San Francisco can finally be put to rest. Today, Apple issued a press release officially announcing that Jobs will deliver the WWDC keynote on June 7th.

The event, which sold out in a record eight days, will take place at the Moscone Center’s West building with Jobs kicking things off at 10:00 AM Pacific. Of course, now that Jobs has confirmed his appearance for the keynote, the real speculation can begin as to what he will announce that isn’t already out there.

The folks at Gizmodo and others have probably already revealed the new iPhone. Fortunately, we haven’t seen the final version of iPhone OS 4.0 and had an exhaustive demo of its features so expect that. Plus, even though Gizmodo supposedly had the real iPhone, there’s no guarantee it was the final design. The phone could look a lot different once its “officially” revealed by Jobs.

Not only that, WWDC isn’t only about the  iPhone, so expect to see some other things announced during the keynote. On that note, here’s a few predictions of what you may see announced by Jobs:

• iPhone 4th Generation with A4 processor (like iPad), more memory and storage. Front facing camera for iChat. Released end of July.

• iPhone OS4 release announced for end of July also.

• New version of iTunes.

• Mac OSX 10.7 Preview. Look for more improvements under the hood and less “amazing” features. Also, may see more of Apple’s move to the ‘cloud.”

• Updated Mac Pro systems.
