I have to invest in new cables for my iPhone and iPad. How long will it be before Apple changes its Lighting cable to something incompatible? Or change to USB 3.1 A to Lighting or Bolt to UBS 3.1 A to Lighting? I also can get Bolt to Bolt to USB 3.1 A adapter to USB 3.1 A cable to Lighting? I would like a Bolt to Lighting adapter. However, I can't find any.
