He's just one Jobs ex among many. A quick tally:

• Palm's financial backer, Elevation Partners, employs Fred Anderson, the former Apple CFO who publicly battled with Jobs over blame for Apple's stock-options backdating scandal.
  
• The company also hired away Apple's former head of Mac PR, Lynn Fox.
  
• Then there was the poaching of Mike Bell, who had been at Apple for 16 years and was senior VP for product development.

Palm's hiring spree grew so annoying to Jobs that he supposedly called up Rubinstein and screamed at him.

Jobs had reason to be agitated. Rubinstein successfully instigated a crash development program that, somehow, conjured an incredibly slick device, the Pre, from a company whose technology had been languishing for years.

In the words of tech blogger John Gruber, "it's quite possible that they have done everything right since" the launch of the iPhone. "Palm designed, built, and released the Pre, WebOS, and an app store, all in about two years."

The Palm team's experience at Apple no doubt helped along the way; it would appear some very detailed knowledge of Apple's iTunes helped allow the Pre to magically sync with the media software, an impressive feat.

The Pre, just released, promises to give Apple's iPhone the most worrisome competition it's yet seen.

And now Rubinstein has his prize, taking control of the whole company from 16-year Palm veteran Ed Colligan. If Jobs needed a catalyst to get him fired up about his return to the helm of Apple later this month, he sure got it.

Amid SEC charges that Apple management had shifted the dates of stock options to benefit executives, including Jobs, Anderson, and former general counsel Nancy Heinen, the company took an $84 million charge in 2006. Jobs and Apple settled a shareholder lawsuit for $14 million, but avoided trouble with the SEC. Anderson and Heinen paid $3.5 million and $2.2 million in fines respectively, without admitting guilt.

The episode caused a major rift between Anderson and Jobs. Anderson had left Apple in 2004, but stayed on the board until the scandal led to his resignation in 2006. In the meantime, Anderson had joined Elevation Partners, a private-equity firm in Silicon Valley. As the stock-options scandal grew, Anderson and Jobs pointed fingers at each other, at one point issuing dueling press releases shifting the blame. Anderson has long maintained that Jobs knew more about the options chicanery than he has let on.

Elevation, which also counts famed Valley investor Roger McNamee and U2 frontman Bono as partners, backed Palm, a rival to Apple in the smartphone business, and recruited a former top Apple executive, Jon Rubinstein, as Palm's executive chairman. No one in Silicon Valley honestly believes this is a coincidence.

Forbes is another Elevation investment. The May 11 story, written by Bill Barrett and teased on the cover, centers on the 118-page transcript of a three-hour interview Jobs gave SEC examiners trying a case against former Apple general counsel Nancy Heinen, which the magazine obtained at some difficulty through a Freedom of Information Act. In the interview with SEC examiners, Jobs complained that the board was not looking out for him and he had to ask for a generous stock-options package, but maintained that he was largely unaware of the backdating and ignorant of the accounting consequences. (Backdating is not illegal by itself, but requires notice to shareholders and a charge to earnings, neither of which Apple undertook at the time it backdated options.)

Excellent journalistic work on Barrett's part. But here's the question: How did Forbes know precisely which document to ask for? It always helps to have well-connected sources. And it's hard to imagine who would be better placed to know the details of the case than Anderson.

Bono is a founder of Elevation Partners, the Silicon Valley private-equity firm named after the U2 song. And Elevation just sank another $100 million into Palm, the troubled smartphone maker. Palm, which waited too long to switch its product lineup from electronic organizers to souped-up cell phones and whose Treo smartphone is showing its age, lost more than $500 million in the most recent quarter. Bono's firm now owns 39 percent of Palm.

He's also lassoed several former Apple executives into the Palm corral. Fred Anderson, a former Apple CFO and board member, is an investor at Elevation. Jon Rubinstein, a hardware executive who served as Jobs's right-hand man at Apple, resigned in 2006 — one day before the company's 30-year anniversary — and joined Palm a year ago. Rubinstein, the company's executive chairman, is working on a new family of devices that will compete with Apple's iPhone; the big unveiling is planned for the CES computer trade show next month.

The last CES was also the scene of the latest dig by Bono at Jobs. In January 2008, he appeared in a farewell video for Microsoft chairman Bill Gates. Later that month, he shilled for Michael Dell, the founder of the eponymous PC maker who once called for Jobs to shut down Apple and "return the money to shareholders." (Apple is now worth far more than Dell. Ha!)

And to think they were once so close. At an Apple event in 2003, Bono called Jobs "the Dalai Lamai of integration." One year later, Bono and Jobs introduced a U2-branded edition of the iPod. Jobs, who is rarely seen in public, attended a U2 concert in 2005, and Bono praised Apple as being "more creative than a lot of rock bands." In 2006, Bono promoted a red iPod for his Product (Red) charity scheme.

So what happened? The falling out has never been publicly explained, but I have a theory on what happened.

Apple's board of directors fingered Fred Anderson, the former Apple CFO, in a probe over stock-options backdating at Apple. In a public statement, Anderson blamed Jobs. Things got messy, and Anderson resigned from the board after reaching a settlement with the SEC.

At that point, Anderson was already at Elevation helping make Bono, whose net worth is estimated in the hundreds of millions of dollars, even richer. So Jobs wasn't just messing with Bono's pal; he was messing with his pocketbook.

It hardly squares with the Irish rocker's saintly save-the-children image, does it?

The defendants knew that options were not granted on the dates that were disclosed to shareholders and falsified the company's records to create the appearance of illegality, and thus bear direct responsibility for their actions.

A previous suit was dismissed because the actions by Apple directors and executives in 2000 and 2001 were too old for courts to consider. We're not sure yet what's so different about this case, except that it's well-timed for bad publicity ahead of the iPhone 3G launch.(Photo by AP/Paul Sakuma)
