The iPhone 5 fever is still prevailing and here comes a rumored news that Apple may soon be coming up with iPhone 5S. It is learned the Cupertino guys have begun working on the next model of iPhone, and probably the new iDevice smartphone is to be named as iPhone 5S.The report of iPhone 5S first struck by way of China based news media Commercial Times. It wrote, “Facing low yield rates in the production of iPhone 5, Apple has accelerated the certification processes for related parts and components for the iPhone 5S.” If this is true, it may be a smart move by Apple. It becomes extremely necessary to switch on to the next version of the iPhone. It is further learned the iDevice giant may start the trial production of iPhone 5S from December this year and the initial capacity of the production is expected to be between 50,000 and 1 lakh units as of now i.e. in the first phase of production. We may not be surprised with this move of Apple as it did the same with iPad 4, the just released fourth-generation iPad. In just seven months after the launching of iPad 3 the iDevice giant came up with the next model. Considering this rationally it may be only after 6 or 7 months gap from iPhone 5 when Apple would launch iPhone 5S. A big question here. Would we be able to see this iPhone 5S during the WWDC 2013?
