Apple can be flexible with the business model it uses to launch iPhone in new markets, has big plans to broaden the platform and is confident it will achieve ten million iPhone sales this year, a senior executive said last night,

Apple's chief operating officer Tim Cook, told the Goldman Sachs Technology Investment Symposium that the iPhone is not married to a single-carrier marketing model, but chose the approach because it made for an easier market debut in the US and other countries.

"We're not married to any business model. What we're married to is shipping the best phones in the world," Cook told delegates at the event. He confirmed plans to launch the device in additional European countries and Asia this year.

Cook also informed that the iPhone Software Development Kit will, "broaden the platform to the point where the only limit will be people's imagination.

"We started by getting developers to focus on Web 2.0 apps. There's over a thousand of these today. But people also want to do more than that. As we got into the phone more and more, it became clear that we should release and SDK. This will make the product even more compelling," he explained.

The iPhone is already an "incredible accomplishment," Cook said, but has far more potential in the long term. "I need a word bigger than 'enormous' to describe it."

On iPod sales Cook countered concerns of market saturation, pointing-out that nealry 40 per cent of iPod buyers in the Christmas quarter were people who did not own an iPod before.

Cook also waxed confident on Mac sales, despite fears of recession, saying: "The ceiling for the Macs is nowhere in sight...Even if the market itself isn't growing, for us, switching Windows users is an enormous opportunity."
