A newly unearthed patent application from Apple shows the design of a reversible 'Type A' style USB connector, detailing its workings and specifications. Such a connector was pictured in the flesh a few days back via famous iPhone component leaker Sonny Dickinson. The official patent application, filed in Feb this year, adds quite a bit of weight to the feeling that the depicted cable is a 'genuine thing'.
Looking at the in-the-flesh connector photos from Sonny Dickinson gives readers a better view of what is on offer with Apple's Type-A modification compared side by side with a regular Type-A connector (as seen above). You can see the inner plastic mounted connection block slimmed down and centralised. Contacts are then placed on either side of the plastic block. Hopefully it wouldn't make the connector (more) prone to breakages.
As mentioned above, it is thought that a new Apple cable with the depicted reversible USB connector on one side and a lightning connector on the other will be in the box of the upcoming iPhone 6 and iPhone 6L. If that is the case we should see it officially revealed in early/mid September.
