Apple CEO Tim Cook has hinted deeper integration with social networking service Facebook, which is coming to iOS, along with the Twitter integration introduced in iOS 5. The news comes at the D10 conference, where Cook talked about a range of potential Apple products.

Cook said the company "could do more with them [Facebook]. Stay tuned." However, he developed the statement after being questioned by co-host Walt Mossberg.

"For us, we want to provide customers simple and elegant ways to do the things they want to do. And, Facebook has millions, hundreds of millions of customers, and so, anybody that has an iPhone or iPad, we want them to have the best experience with Facebook on those platforms," Cook said.

On the question of whether Facebook is "onerous," as Steve Jobs once called the company, Cook said "they have their own way of doing things."

Some users wondered why Apple didn't integrate Facebook into iOS 5 but, as The Verge noted, the demand of iOS users could force integration despite company differences. Facebook has 900 million users, and is now a public company. With the stock price for the company dropping, integration with Apple - the company is approaching a $1000 share price - could help the social networking giant.

Cook also touched on companies Apple buys, and whether more will be purchased under his tenure. He said Apple continues to buy companies, and may reveal acquisitions depending on the size and price. "If I don't have to I don't," he said.

"I feel strongly that being secretive on the product side of our business is so important," he added. Cook added any company, and its software, wouldn't be acquired purely for revenue. Instead it would be because of the technology, the people and the IP or even putting the people on another project. Apple acquired technology to bring Siri, its voice recognition technology, to iOS  along with the iPhone 4S.

Cook reiterated that fans should "stay tuned" on the news, hinting we could see something special at WWDC, which begins June 11.
