Interesting discoveries The app that regularly shares the app Demo An interesting little discovery from the Twitter account: Here are prototypes of lightning cables numbered PROTO4, with a logo on one side of the sheath that protects the connector electronics. This symbol is reminiscent of the current on the 30-pin connector (instead of lightning), which was used to indicate the insertion direction to the iPod and iPhone. Does this mean that you need to connect the lightning connector in a particular direction?

The Lightning differs greatly in size from its predecessor, as well as the fact that you can insert the connector in any direction. It was one of the main sales outlets Apple put forward to comfort everyone who was lamenting the change at the time (accessories needed to be purchased).

The prototype consists of 8 pins that are accessible from both sides of the connector, making the presence of this symbol surprising. Anyway, at the same time that the new connection was launched in 2012, it disappeared like the iPhone 5.

Update – We were told that there are lightning and USB-C cables in the specific inclusion direction that Apple technicians use internally.
