Around 2009, when the lower cost version of iPhone appears, Business Week believes the yearly market for iPhones could be over 10 billion dollars a year. Its an interesting prediction; if those numbers come to pass, iPhone could become a bigger source of revenue than the traditional iPod. 'The answer may not come until 2009. By then, Apple should have begun creating lower-cost iPhone variants to reach consumers scared off by the introductory $499 price. It also will probably have moved into overseas markets and cut deals with more carriers to utilize higher-speed wireless networks. So while most analysts look for Apple to sell around 3 million units this year and 10 to 12 million in 2008, many figure that 20 million will move in 2009.'"
