Multiple reliable sources have confirmed to iLounge that Apple has made significant changes to its Made For iPad/iPhone/iPod (MFi) policies, tightening control over the manufacturing of Lightning accessories. According to the sources, only Apple-approved manufacturing facilities will be allowed to produce Lightning connector accessories, even including third-party accessories. Moreover, Apple hasn't approved any factories yet, which the sources say will limit the number of Lightning accessories available in the near future.
In addition, the site has learned that Apple plans to hold a MFi "seminar" in November in China where it will discuss changes to the program. The late timing of this seminar likely means manufacturers will not have time to produce any products until after the holiday season.
Finally, its said the the Lightning connector has proved very difficult to copy and companies that were originally offering cable pre-orders have been forced to cancel those orders.
