Video Shows New Lightning Cable with Reversible USB Connector in Action
Apple could start shipping a new Lightning cable alongside the next wave of iOS device releases this fall, which will likely start with the iPhone 6 next month. It is unknown if the updated cable will contain any new features aside from a reversible USB connector, although past rumors have pointed to support for high-definition audio playback.
An Apple patent discussing a reversible USB connector was also published last month, and discussed a more user-friendly design compared to current cables. However, it is unknown if this new cable will face challenges from the likes of California company UltraTek, which already holds a patent itself for a reversible connector and currently sells cables through major online retailers.
