Patently Apple reports on some new patent applications that appeared in China's patent database this week. One diagram (above) clearly shows an Apple iPad with dual 30pin dock connectors allowing both landscape and portrait docking orientations. While the site seems to think this represents the next iPad, we feel it most likely represents existing designs that never made it into the current iPad. While the distinction may be subtle, it could mean we may never see this design in a future iPad.
In fact, dual dock connectors were strongly rumored for the first generation iPad by iLounge.
The site also identifies the top sensor as a possible front-facing camera, though it seems more likely to represent the iPad's ambient light sensor which is located in that spot.According to the site, the tablet will have two dock connectors to allow the device to be docked in either portrait or landscape orientations. This should allow the device some flexibility when docking with 3rd party accessories, avoiding awkward cable positioning.
