Macotakara reports that the long-running Japanese magazine MacFan has claimed that Apple will be holding a special media event on June 20 to introduce the iPhone 5S. According to the report, the iPhone 5S will actually launch in July with the rumored lower-cost iPhone following in August. Various analysts and other sources have been indicating that the iPhone 5S could launch as soon as June or July, but MacFan's specific claim of a June 20 media event seems to defy common sense on several levels.
