Shaw Wu, an analyst at Kaufman Bros. has documented by sources in the supply chain of Apple that the company is working on several models of iPhone equipped with new screen sizes:
Our sources believe that these rumors represent the arrival of a new business model: iPhone low and high-end complement to an intermediate iPhone 4. An iPhone “mini” or “nano” would be plausible in the wake of the latest iPod nano.

We believe that Apple is opting for the wisdom to offer alternatives to an iPhone 4 appeals only to users of middle class / high. Articulate a phone line to three bands as is done with the iPod you can extend its range of buyers and make things even more difficult to competition.
