The next-generation iPhone will launch with "at least two screen sizes" as options, says Topeka Capital Markets analyst Brian White. The claim is based on a meeting with a company in Apple's supply chain. White argues that the new phone could potentially even launch with as many as three different sizes. "We believe Apple is coming around to the fact that one size per iPhone release does not work for everyone and offering consumers an option has the potential to expand the company's market share," he writes in an investor memo.
