New speculation by KGI Securities analyst Ming-Chi Kuo has a new flagship iPhone "5S" model arriving in early summer, alongside a redesigned version often referred to as a "low cost" iPhone because it will be more affordable in instalment payments than the current price of a new iPhone model, and made of cheaper materials. The new iPhone models, he says, will also be compatible with China's TD-DLTE and TD-SCDMA networks, be offered by China Mobile, and will offer a host of new features -- reiterating his earlier predictions.
