There's been a lot of speculation about the Apple Inc. (NASDAQ:AAPL) iPhone 5 successor, which is expected to make its debut this year. But besides the company releasing a pure iPhone 5 follow-up this year -- the rumored iPhone 5S, with the "S" standing for security (hint: integrated fingerprint sensor) -- one Wall Street analyst now feels very confident the firm will also release a "low-cost" iPhone (iPhone 6) in 2013.
