SAN FRANCISCO -(Dow Jones)- Gerald Lee attended Apple Inc.’s(AAPL) annual shareholders meeting on Wednesday for one main reason: To get whatever information he could about the health of Chief Executive Steve Jobs, who unexpectedly took a six-month medical leave last month.

He didn’t get much.

“I left the way I came in, not knowing a whole lot,” Lee, a San Francisco resident, said after the one-hour meeting.

Apple shareholders have called for more details on the state of Jobs’ health, as well as the company’s succession plans. Jobs, a pancreatic cancer survivor, surprised investors last month, when he suddenly announced his medical leave, saying his situation was “more complex” than initially thought.

Jobs’ health is considered a critical element in determining the price of Apple shares because of the outsized role the CEO plays at the computer maker. Though many CEOs are highly recognizable, few are as important to their companies as Jobs is with Apple. The executive is both the face of Apple and its chief innovator.

Over the last six months, investors have looked for any clue on the state of Jobs’ health. On several occasions, his gaunt appearance has sparked selloffs in the company’s stock.

Many of the investors who flocked to Apple’s Cupertino, Calif. headquarters for the meeting came away dissatisfied. Among the questions they wanted answered explicitly: Will Jobs be back at June as expected and will he have the same workload if he is?

Much of the information given by the board at Wednesday’s meeting is already publicly available. Genentech Inc. (DNA) Chief Executive Arthur Levinson, tasked with answering the inevitable questions about Jobs’ health, said he was confident the board had met its disclosure obligations regarding the founder’s health. He added little specific about who might eventually replace Jobs and when that might be.

“Succession planning is something this board takes up regularly,” Levinson said. “You can assume we will do that responsibly.”

That wasn’t enough for some investors.

“He is a significant asset, and anything of significance that’s happening to him should be disclosed,” Louis Malizia, who represented the International Brotherhood of Teamsters, said of Jobs after the meeting.

Apple shares ended Wednesday’s regular session 1% higher at $91.16. In after- hours trading, they continued rising to $91.30.

Apple has issued Security Update 2008-002 v1.1 (Leopard) and Security Update 2008-002 v1.1 Leopard (Server), recommending these revised security patches to all users.

The updates, which weigh in at 50MB and 108MB respectively, are described as improving Mac OS X security and incorporating all previous security updates.

Apple introduced its slightly revised security update to grapple with a problem found when using Aperture under the preceding one, which exposed some undisclosed reliability issues in the Printer Settings button in Aperture 2.0 on Macs running OS X 10.5.2.

The update is available through Software Update or for direct download from Apple’s Web site.

The new version of the SDK includes Interface Builder, a component of Apple’s development tools that lets developers create the interface for their applications.

Apple released on Thursday a new version of its iPhone SDK for developers. iPhone SDK beta 2 includes Interface Builder, a component of Apple’s development tools that lets developers create the interface for their applications.

That seems to be the only major change in the latest build, according to the SDK’s read me, which continues to list some known issues. Apple says “this second beta is known to be incompatible with installation folders other than the default /Developer.”

Given the importance of UI on the Mac, Interface Builder is a pretty critical tool in the development process, and some developers had chosen to hold off on their efforts until the SDK was revised.

Apple unveiled the iPhone SDK at a special event earlier this month, allowing developers to begin building applications for the iPhone and iPod touch. Several high-profile companies have already jumped onboard, demoing their applications at the event.

Highlighting the demos was AOL with a native AIM client; other applications from Electronic Arts, Salesforce, and Apple were also shown.

Eight months ago, Apple was a nonplayer in the mobile space. Now, according to Apple, iPhone is the second most popular smartphone solution after BlackBerry. With all the hoopla he raised over iPhone at launch time, it’s as if Steve Jobs saw this coming. What he admits he didn’t see coming was the market’s reaction to the lack of a software development kit (SDK) that would support third-party apps on iPhone. iPhone is the only smartphone platform without custom application support, and that fact locked Apple out of the fleet sales that are RIM’s bread and butter. It also disenfranchised the Mac developers who put Mac on the map and keep it there with, wouldn’t you know it, native applications. I have weighed in on the subject of an iPhone SDK for native software in my usual soft-spoken, dead-horse-friendly way. “Apple, don’t brag that iPhone runs OS X,” I said, “until developers can get at it.”
