There have been a lot of rumors about Apple's upcoming smartphones. Even if the company doesn't announce the much rumored budget iPhone, it is definitely going to launch the successor to the iPhone 5. Ever since it released iPhone 3GS after the iPhone 3G, the company has released a smartphone with minor changes and the “S” label every other year. Since it launched the iPhone 5 last year, there has been a lot of speculation that the upcoming smartphone will be called iPhone 5S. The moniker for Apple's upcoming smartphone has apparently been “confirmed” by Japanese carrier KDDI.
