No one knows for sure, of course, but two reports are again suggesting that Apple will be releasing two iPhones this fall: an iPhone 5 with a larger screen and an iPhone 4-plus, a lower-cost phone for the pre-paid and international markets. One report, from an analyst with JP Morgan and summarized on AppleInsider, describes the two phones. He says the iPhone 5 will also be thinner and lighter in addition to having a larger retina display.
