The Tuesday report came from DigiTimes. It said that Apple was planning to release two 4-inch iPhones this year. One of those would be a follow-up to the current iPhone 5 (an iPhone 5S?), and the other would be the long-rumored lower-cost iPhone that could compete with Android devices in emerging markets.
Meanwhile, a larger-screened iPhone is in the works, but will not be shipped until 2014, said the site, which sources its information from Asian upstream parts suppliers. DigiTimes had earlier said a larger-screened iPhone was coming this year, also adding that it would be the lower-cost model, not the higher-end one.
It is early in the rumor season, but the new report contradicts a Monday report from the China Times. That report said the larger screen, codenamed "iPhone Math," would ship this summer as a third new iPhone handset, alongside the iPhone 5S and the lower-cost model iPhone. The publication claimed it could launch in June with a 4.8-inch display, which would put it in the Galaxy S III range in terms of screen size, though Apple may still opt for an elongated slimmer display.
Other rumors that have emerged thus far this rumor season include Apple shipping an iPhone with multiple case colors, akin to phones like Lumias. The lower-cost iPhone is also in the mix of rumors, and is expected to ship with a cheaper, plastic case and perhaps older components to keep the price down.
