Kara, Walt and Katie Visit iPhone 4-Palooza at WWDC–With Special Guest Stars Schiller, Pincus and More!

Earlier today, BoomTown hoofed it to downtown San Francisco to join a pair of All Things Digital A-Team members–Walt Mossberg and Katie Boehret–at Apple’s Worldwide Developers Conference, where CEO Steve Jobs unveiled the newest version of the iconic mobile device, iPhone 4.

As usual, I had to snark it up with a video of the proceedings at Moscone Center West, where over 5,000 of the Apple (AAPL) faithful gathered to kibitz and ogle.

Cue the excessive oohing and aahing.

A very playful Jobs–who even handled a networking connection snafu with unusual restraint–gave them a lot to talk about, from the iPhone 4′s FaceTime video chat to its squarish, stainless-steel-and-glass new design to multitasking to an even crisper screen called Retina Display.

(Memo to Katie Cotton: Is the iBall the next secret Apple project? Because Retina Display, frankly, sounds a little too much like the corrective LASIK eye surgery I have been avoiding.)

Also on the menu: Some more info about iAds, which is competing with Google (GOOG) in the nascent but fast-growing mobile advertising market.

Jobs threw in a few light jabs at the Silicon Valley search giant, although it was pretty tame overall.

Interestingly, I was just at the same venue for Google’s I/O developers event a few weeks ago, where that company was showing off cool new features for its Android mobile operating system, all while dissing Apple.

In any case, like that one, it was another big day for the smartphone market and users, as Apple tossed off its newest innovations. Presumably, the ball is now in Google’s court.

Until Google swings back, here’s my video, including interviews with top Apple execs Phil Schiller and Katie Cotton, as well as Zynga’s Mark Pincus, who demoed a new iPhone version of the start-up’s FarmVille online game:
